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 ...

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 ...

Qualcomm Inc.QCOM recently appealed to the U.S. telecom regulator, Federal Communications Commission (FCC) for Special Temporary Authority (STA) to conduct limited antenna pattern testing of satellite ...

No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer. Prior to its invention, measuring the response of an antenna system was more or ...

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 ...

Antenna design, fabrication, and performance verification are key to the success of both the astrophysics program and the satellite telecommunications program. To support these efforts, a free space ...

No audio available for this content. More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS ...

With the completion of its new, state-of-the-art testing facility this summer, Winegard, a world leader in the design and manufacture of innovative antenna products, will soon establish itself as a ...

A very low-tech way to make field recordings. The process I was intending to follow was simple enough. Set up the antenna in the middle of the field, have it transmit some RF, and measure the signal ...

Many of the projects we link to here at Hackaday have extensive write-ups, pages of all the detail you could need. Sometimes though we happen upon a project with only a terse description to go on, but ...
