Anechoic Chamber Alternative

Test multiple design iterations and optimize antenna designs at your lab-bench in seconds without wasting time waiting in congested anechoic chamber lines.

If you are not trying to pass a compliance test, why lose valuable project time waiting in line to test your designs in expensive anechoic chambers?

80% of our customers (most leading smart phone manufacturers, military contractors and consumer electronics manufacturers) own at least one anechoic chamber in-house. To address time-to-market pressure and to increase R&D productivity they integrated RFxpert into their test facilities to measure antennas quickly and cost effectively.

Why do they need the low-cost, bench-top RFxpert if they already have an anechoic chamber in-house?

They execute real-time analysis of their embedded antenna designs, test multiple design iterations and optimize complex embedded antenna designs at a desktop in seconds at each stage of the design process.

They gain insights about why designs fail that cannot be provided by an anechoic chamber.

RFxpert’s unique near-field data provides insight into the root cause of problems.

They reduce operational costs by diagnosing and debugging pre- and post- compliance test problems using RFxpert instead of anechoic chamber.

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

  • Analyze your embedded antenna designs.
  • Prototype & test new designs, components and forms.
  • Test & optimize several iterative embedded antenna designs.
  • Review effects of different packaging materials & layout changes.
  • Verify final product performance in real-time

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

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.

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
“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

“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”
