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 ...

If you’ve ever worked at a station that’s installed a new antenna, you’ve probably wondered how well the antenna’s real pattern matched the nice clean pattern supplied by the antenna manufacturer. The ...

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 ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

Radiation patterns for antennas can be utterly confusing, especially when presented in two dimensions, as they usually are. Fear not, [Hunter] has your back with 3D printed and color-coded radiation ...

The author is with Cavell Mertz & Associates Inc. in Manassas, Va. May 2018 marks our first year for the measurement drone project development, which is now in operation for measurement of VHF and UHF ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...

THE ANTENNA. This crucial component of any radio transmitting or receiving system has a history that actually predates the invention of radio itself. The first antennas were used by Princeton ...
