More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS antennas because of the stronger impact ...

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 ...

It is well known that the phase center of a GNSS antenna can vary with the satellite direction. This phase center movement leads to aspect dependent carrier phase and code phase biases in 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 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 ...

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 ...

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 ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. On California’s Mt. Wilson, dual RFS broadband panel arrays provide sculpted digital/analog ...

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 ...

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, ...
