Antenna vs. Frequency Selective Filter

From the electrical engineering perspective, a filter is a device that passes signals of interest in the desired frequency band while discriminating other/undesired frequencies.

An antenna is typically considered a transducer device, which converts guided electromagnetic waves to spherical waves.

Both filters and antennas are typically passive devices and reciprocal (i.e. input and output can be swapped).  What is less known about antenna, yet can be mathematically shown is that it behaves as a “spatial filter”.

From the Fourier Transform theory, we know that a narrow pulse, in time domain, has a wide frequency/spectral content (i.e. time and frequency are reciprocal to each other).   To pass such a narrow pulse signal, a wide band filter is required.  Similarly, a narrow far-field antenna radiation pattern requires to pass wide “spatial frequencies”.  In other words, the antenna has to be electrically large (i.e. relative to wavelength). That is why, in the radio astronomy community, an antenna is viewed as “spatial filter”.

Antenna Surrounding

Antenna performance not only depends on its design topology but also on the surroundings which impacts antenna impedance in real world application.

In other words, if one were to design an antenna and meets all its required performance in standalone condition, then when it is embedded with other radio components, the antenna behavior would change, either over frequency or for worst.

In fact, mobile handset antennas are tuned with human phantom after fabrication, to adjust tuning elements in such a way that meets requirements in presence of the human body.

More advanced mobile handsets have capability of adjusting the tuning elements on the fly to account for various surroundings and still meets acceptable antenna performance.

Very advanced mobile handsets have capability of adjusting impedance and aperture tuning elements on the fly.

Antenna Geometry Scaling

Antenna physical dimensions have always been challenging.

In fact, number one reason that radio frequencies, RF are used for radio communication is the antenna size for handheld devices.

That’s in order for our mobile radio or mobile phone to wirelessly connect, the radio frequencies must be utilized to physically realize an antenna.

Human audio frequency is anywhere from 20 – 20 KHz, which prohibits any handheld device antenna.

This is the history of radio frequency.

Now let’s fast forward to future, where 100 GHz to multi-THz radio are sought.

The outlook for Microwave or Nanowave signals may require another challenge yet in opposite to miniaturization.

At these frequencies it may be required and challenging to physically realize a much larger antenna than the operating wavelength.

Broadband vs. Multi Band Antenna

Broadband antenna radiates over wide continuous bandwidth with acceptable radiation performance.

In general, antennas are reciprocal device, i.e. their radiation performance is the same regardless whether they are used as receiver or transmitter antenna.

Therefore, any statement about antenna can be taken as either receiver or transmitter antenna performance.

Multi Band antennas are radiator that have acceptable radiation performance over discrete (non-continuous) bands.

It is fallacy to assume that broadband antennas are preferred over multi band antenna.

Think of multi band antennas as frequency selective filter outside of their operating radiating frequency inter-band.  Therefore, technically, multi band antennas have two objectives, first to radiate in the bands of interest.  Second, they filter out of inter band or undesired signals.

Product definition is the most important scoping part of any consumer electronics and comprised of Architecture, Antenna /ASIC /Algorithm of all systems or applications.

Antenna Loading

Antenna loading is a generic term and pertains to various configurations.

Here are some examples.

Mobile phone or headset antennas are typically designed for operating frequency range using antenna CAD tools.

Once designed and built, their matching network needs to be tweaked to real application of the antenna surroundings.

The mobile phone antenna is loaded with human phantom, effectively salt-water container to mimic human head.

The antenna input impedance would change due antenna surroundings, consequently the antenna de-tunes, e.g. the resonance frequency changes.

Depending on the de-turning, either the antenna impedance matching needs to be tweaked or antenna structure need to be resized to account for the loaded antenna.

For frequencies where wavelength is larger than the physical available structure, typically smaller antenna is designed with inductive loading.

The inductive loading is to cancel out the capacitive part of antenna impedance.

This is applicable as long as the real of antenna impedance is considerable for radiation, i.e. radiation efficiency.

If the desired radiation efficiency is not achievable, that implies the antenna may need to be resistive loaded to increase impedance matching whereby improves radiation efficiency.

iPhone 4 Antenna issue, aka Antennagate

It is well known that antenna surrounding impacts the antenna performance.

Somehow that critical antenna engineering and science was missed or ignored during iPhone 4 original design product.

The antenna issue surfaced when the users were holding the iPhone 4 in a certain way, the radio signal significantly diminished or lost completely.

One could say that it was not an antenna issue yet a product issue as the antenna integration into the iPhone 4 mechanical casing was too close to the user holding it.

Once the issue was acknowledged and understood by the stakeholders, the short-term mitigation was to issue free Apple designed iPhone case.

Although the iPhone case appeared minor yet it added additional space between the user and antenna, consequently mitigating the antenna surrounding issue somewhat.

Apple naturally investigated and looked for more robust solution to address the antenna issue.

From Business Goals to Measured Antenna Performance
Why System-Driven Antenna Design Protects ROI

For any radio or radar system to perform as expected, it must begin with clearly defined use cases and operating expectations.

Use cases define what the system is designed to do, under which conditions it must operate, and how success will be measured. Ultimately, these use cases exist to fulfill business goals—whether that is performance differentiation, cost targets, deployment constraints, or return on investment (ROI).

In practice, use cases sit at the intersection of business objectives and system definition.

Modern radio and radar systems are inherently multidisciplinary. They are composed of three tightly coupled engineering domains:

  • Antenna
  • ASIC / Hardware
  • Algorithms / Firmware / Software

Decisions made in one domain directly affect the others. As a result, antenna design cannot be treated as an isolated activity—it must be driven by system-level requirements and validated continuously against both technical and business objectives.

A Hierarchical Antenna Design Flow

The antenna design flow illustrated above shows a top-down, closed-loop process that connects business intent to measured antenna performance:

  1. Use Cases Derived from Business Requirements
    The process begins by translating business goals into concrete system use cases.
  2. System Requirements Definition
    System-level requirements are established across antenna, ASIC, and algorithm domains to ensure architectural alignment.
  3. Antenna Requirements
    Electrical, mechanical, environmental, and integration constraints are derived directly from system requirements.
  4. Antenna Design and Simulation
    The antenna is designed and simulated to verify performance against requirements before fabrication.
  5. Implementation and Fabrication
    The design is realized in hardware, accounting for materials, packaging, and manufacturing constraints.
  6. Measurement and Validation
    Measured performance is compared against simulations and requirements, closing the loop and validating ROI assumptions.

This hierarchical approach ensures that antenna performance is not only optimized in isolation, but validated against system requirements and business goals at every stage.

Why This Matters

Many antenna programs fail not because of poor electromagnetic design, but because of misalignment:

  • Between business goals and system requirements
  • Between system requirements and antenna specifications
  • Between simulations and real-world measurements

A structured, system-driven antenna design flow reduces technical risk, prevents late-stage surprises, and protects time-to-market.

Antenna Design, Audit, and System Validation

From Physics to Product

The Challenge

Defining an antenna is deceptively difficult.

Even the IEEE Standard for Antennas avoids a single, formal definition—because an antenna is not just a component.
It is the boundary between circuits, electromagnetics, and free space.

In practice, antenna failures rarely come from radiation physics alone. They come from:

  • Unclear system boundaries
  • Incorrect assumptions at the feed, interface, or environment
  • Misalignment between RFIC, antenna, and system teams
  • Validation performed too late—or against the wrong metrics

When this happens, performance gaps appear only after integration, certification, or field deployment—when fixes are most expensive.

ORTENGA’s Approach

ORTENGA treats the antenna as a system interface, not a standalone radiator.

We analyze antennas from three synchronized perspectives:

  • Electromagnetic: guided waves transitioning to radiated fields
  • Circuit: impedance transformation from transmission line to free space
  • System: interaction with packaging, platform, environment, and use case

This unified view ensures antenna decisions align with real system constraints, not isolated simulations.
