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 ...

The authors are president and vice president, respectively, of Communications Technologies Inc., a consultancy in Marlton, N.J. Fig. 1: Measured vertical (purple) and horizontal (blue) field strength ...

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 ...

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 ...

In the evolving landscape of wireless communication, reconfigurable antennas are gaining significant traction due to their ability to adapt radiation characteristics such as pattern, frequency, and ...

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 ...

Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a laboratory has been a very difficult process — dynamics were limited and test duration was usually short. Often, dynamic ...

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, ...
