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:
- Experiments that lead students through basic antenna measurements using RFxpert (radiation pattern measurements, looking at near fields, etc.)
- Experiments that show how modification of the layouts would affect antenna resonance (requiring a VNA), current distribution, and radiation pattern
- 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
- Background and Definitions
- Measurement Devices
- Printed Monopole Antenna
- Printed Inverted-F Antenna
- 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:
