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 ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

I'm looking at an antenna I currently have in use and the main source of RF energy I should be receiving is generated off one of its side lobes. I'm trying to do an academic study to better my ...

This is the third in a series of articles about FM transmission systems. In the Oct. 23 installment, we looked at the question of antenna gain vs. transmitter power. In this segment, we will discuss ...

Usually, bigger is better. But in the case of AM towers, taller is not always better. A very tall AM radiator is not always the best radiator. In fact, without a considerable amount of expensive work, ...
