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 classic horn antenna undergoes some tough analysis and emerges with improvements that increase the frequency band to 3 GHz. The dual-ridged horn antenna (DRHA) is a workhorse in EMC and antenna ...

QuadSAT, a Danish startup that uses drones for the test and measurement of satellite antennas, has scaled up its ambitions: it reports successfully completing a measurement campaign of large antennas ...

A current Radio World ebook explores trends in the use of AI in broadcast radio technology. In 2022 the Federal Communications Commission allowed computer modeling of directional FM antennas. The ...

The FCC TVStudy OET-69 software includes the ability to run studies using actual antenna azimuth and elevations patterns, but it wasn’t until release of Version 1.2.8 that there was a way to apply ...

Peter Delos, Technical Lead, Bob Broughton, Director of Engineering and Jon Kraft, Senior Staff Field Applications Engineer, all with Analog Devices. With the proliferation of digital phased arrays in ...

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 going to go out on a limb here and start with a statement: In the real world, there is no such thing as a non-directional FM broadcast antenna. An isotropic radiator may be theoretically possible, ...
