Antenna Pattern Measurement in Seconds

RFxpert is the only real-time, compact, bench-top antenna measurement device.

Interactive educational tool: real-time measurements!

EMSCAN products are powerful educational tool thanks to real-time graphic-oriented data; interactive measurements; compact size and unlimited software licenses.

The educational discount makes the RFxpert an ideal and economical research tool.

Powerful educational tool: live demos in the classroom!

The RFxpert is the perfect equipment to support RF and antenna education. It is a family of antenna measurement tools to quickly evaluate and optimize antenna designs. You can characterize antenna performance in real-time on a lab bench-top, in the 300 MHz to 6 GHz range. Its compact size and unrivalled speed enables live demonstration in the classroom.

Antenna design and test lab kit for the class!

To complement the RFxpert family, EMSCAN is pleased to offer a complete Antenna Design and Test Lab package that includes lab material for students and professor, one kit of antennas, the design files to produce as many of the same antennas as needed and some theoretical background material from Dr. Edward Joy.*

The license to copy the material for students and professors, and the antenna design files is on a per campus basis.

The antenna measurement lab material comprises the following:

  1. Experiments that lead students through basic antenna measurements using RFxpert (radiation pattern measurements, looking at near fields, etc.)
  2. Experiments that show how modification of the layouts would affect antenna resonance (requiring a VNA), current distribution, and radiation pattern
  3. Experiments that show how to load antennas with lumped components to change resonance, current distribution, radiation pattern or to make them tunable (varactors)

Table of contents

  1. Background and Definitions
  2. Measurement Devices
  3. Printed Monopole Antenna
  4. Printed Inverted-F Antenna
  5. Patch Antenna

Antennas include monopoles, PIFAs (the most commonly used antennas in cellphones), and patches. These are basic antenna geometries that can easily be fabricated in standard PCB technology.

* Dr. Edward Joy is Professor Emeritus of Electrical and Computer Engineering at Georgia Institute of Technology where he received his B.E.E., M.S.E.E. and Ph.D. degrees in Electrical Engineering. During his Ph.D. studies he was recognized as Research Fellow for Schlumberger, NASA and Scientific Atlanta.

He currently teaches three course: Antenna Engineering; Far-field Anechoic Chamber; and Compact and Near-field Antenna Measurement Techniques and Near-field Antenna Measurement Techniques.

How accurate is the result compared to a CTIA anechoic chamber?

RFxpert measures the characteristics of an antenna in one second compared to hours (including the set-up time) in an anechoic chamber. RFxpert accuracy is +/- 1.5dB. Below are comparative test results:


Efficiency comparison in the range of 1700 – 2200 MHz done by a reputable cell phone manufacturer


TRP comparison of a WCDMA device for Bands 5 & 6 done by another reputable cell phone manufacturer


Base Station Antenna comparison at 1950 MHz done by a cell phone service provider


Why RFxpert Is Right For You

You want to avoid the delays and set-up needed for far-field measurements in a chamber.

RFxpert not only require low CAPEX and zero OPEX, they also deliver significant ROI advantages.

You can execute real-time analysis of your design, test multiple design iterations and optimize complex designs on your lab-bench in seconds at each stage of the design process.

Key Benefits

Are you under time-to-market pressure because of the countless number of lengthy measurements in inaccessible anechoic chambers?

Tired of losing valuable project time waiting in line to test your designs in expensive anechoic chambers?

Do you want to test your design and performance quickly to accelerate project completion and delivery?

Are you under budget pressures?

Why did your product fail the compliance test in an anechoic chamber? Why didn’t you see this coming?

With RFxpert, in seconds and a fraction of an anechoic chamber cost you can easily:

  • Analyze your embedded antenna and wireless device designs
  • Prototype / test new designs, components, and forms
  • Iteratively test and optimize embedded antenna designs
  • Perform highly repeatable and rapid over-the-air wireless device measurements
  • Verify final product performance in real-time
  • Gain immediate insight into the root causes of performance issues by analyzing the near-field results

…all for a fraction of the cost of an anechoic chamber.

  •   How does RFxpert work?

    rfxpert-how-does-it-workRFxpert measures the magnetic field (H-Field) in two orthogonal directions using H-field probes and projects this data to the far-field using the planar aperture distribution to angular spectrum transformation or plane wave spectrum (PWS) transformation.

    A second custom algorithm then adjusts the far-field projection to eliminate the predictable coupling effects of the measurement array of probes. Probe response compensation is also taken into consideration in this algorithm.

    EMSCAN meticulously developed this custom algorithm through comprehensive and rigorous R&D efforts to get the most accurate test results.

Companies Who Trust RFxpert Products
What Our Customers Are Saying
“The addition of the RFX2 system to our RF design and test capabilities has enabled us to deliver better antenna and RF designs to our clients, and ultimately to our clients’ users.”
Charles Manry, Senior RF Engineer, PhD
Synapse Product Development
“I prefer to use the RFxpert for my antenna design projects instead of simulation software. In a couple of hours, I can model a real antenna out of copper and test it with the RFxpert in the antenna’s intended operating environment. I then use the proven design, based on the RFxpert analysis, to prepare a CAD drawing and send it off to manufacturing for prototyping.”
Jorge I. Ortiz
RF Network & Antenna Engineer, Independent Consultant at Mueller Systems Ocala, Florida Area
“We're impressed with the accuracy of the RFX scanner compared to our external lab measurements for TRP.”
Jeremy Monroe
MoJoose Inc
“We wanted to extend the distance between the hand-held transmitter and the aerial device. Initially we thought that we had to add an additional power amplifier stage. The RFxpert showed us that the real problem was something else: the coax was radiating as much as the antenna. By using better coax and a different coupling method from the final power amplifier stage to the antenna, we were able to transfer more power to the antenna. We managed this significant increase by almost zero cost to the design.”

“Designers now evaluate designs in real-time vs. waiting at the back of the queue with $100M+ projects in front”
