Last year the FCC changed its rules to make it significantly easier for FM radio broadcasters to verify their directional patterns. The report and order gives FM and low-power FM applicants using ...

When [Jephthai] wanted to build his own Yagi antenna, he turned to MMANA software for antenna modeling. This is an antenna analysis program that uses the moment method to calculate parameters for ...

The UK’s CarbSAR satellite is set to revolutionize Earth observation with a uniquely crafted radar antenna. Unlike ...

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...

A model that predicts the radiation pattern from patch antennas in real installations could take the guesswork out of communication device development. A model that predicts the radiation pattern from ...
