Compact system measures antenna patterns, TRP without anechoic chamber

May 16, 2016

MegiQ has introduced a portable, compact radiation measurement system that allows wireless developers to measure (antenna) radiation patterns and TRP of their RF device from 700 MHz to 4 GHz.

The RMS-0740 consists of a turntable and a measurement unit and is optimized for measuring devices without the need for an anechoic chamber. A moderate lab space is sufficient to get accurate three-axis radiation patterns and TRP calculation. The RMS-0740 is claimed to give a true insight into the RF performance for a significantly reduced budget and in just minutes, which enhances the performance of the product and the customer satisfaction in the field.

Extensive testing and comparing with measurements from an anechoic test lab shows that the measurement accuracy of the RMS-0740 is in the same order as anechoic measurements. The application software makes the measurement flow straightforward and includes storage and reporting of the results. Results can be presented in Field Strength, ERP and antenna gain. Total Radiated Power and other statistics are calculated from three rotations.

There is a lightweight turntable for small products and a heavy duty table for larger devices. Devices can be measured standalone in constant carrier mode, and a separate generator output allows for full characterization and frequency sweep of custom antennas and prototypes. The measurement unit has a dual channel receiver that allows measuring two polarizations in one rotation. This cuts test time in half. A three-axis measurement takes less than two minutes!
