With their professional performance and affordable price, MegiQ VNAs are perfect for setting up microwave labs and training courses at universities. The Complutense University of Madrid has a good experience and is now expanding their capacity with more MegiQ equipment.

Measuring radiation patterns from wireless designs with antennas normally requires a rack of test gear, but this system does the job in a moderate-sized room without an anechoic chamber.
This article discusses how the MegiQ RMS-0740 can be an asset in wireless development, without the hefty investment in an anechoic chamber.
Developing wireless products can have pitfalls if you don’t know what to look for. Antennas are not just components, they need to be implemented with attention to their application and environment. Not only should the antenna impedance be matched but also the radiation pattern should meet certain criteria.
Developers of wireless products that need to push to the higher communication bands now have access to an affordable VNA for operation up to 6GHz. The new MegiQ VNA-0460 VNA measures impedances and other S-parameters from 400MHz up to 6GHz.
MegiQ introduces a portable, compact Radiation Measurement System that allows wireless developers to measure (antenna) radiation patterns and TRP of their RF device from 700MHz to 4GHz.
MegiQ introduces an Application Programming Interface (API) for their popular series of VNAs. With this API, programmers control the measuring process and data flow to integrate RF testing in production tests or specialized VNA measurements. This makes it possible to implement a very cost-effective solution to S-parameter verification in production testing.
Although a very good design will help to achieve high yield on antenna performance, batch to batch tolerances in PCB and components can suddenly influence resonance frequencies of on-board antennas.
There is an easy way to determine the resonance frequency by wireless without having to probe electrically. Just as with the old grid-dippers
