Most readers will be aware that a good way to extend WiFi range is to use a better antenna for those 2.4 GHz signals, but at the same time such high frequency hijinks have something of a reputation of ...

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 ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical near-field antenna range. The 1,260-square-foot indoor range, lined with radio ...

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 ...

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 ...

Long time readers know I like to test compact and, where possible, low-cost equipment. Recently I found another tool to add to my backpack when I get back on the road. Seven years ago, wanting a ...

In recent years, many of my clients have been developing products that incorporate wireless and cellular communications into IoT products. I’ve also been partnering with a local CTIA-approved wireless ...

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 ...

The antenna testing chamber, lined with radio frequency and microwave foam absorbers, is equipped to accurately sample the near field of an antenna. Those measurements are then mathematically ...

A couple of years ago, independent European test laboratory Broadband-Testing put six of the then most popular high-end smart phones to the test and was surprised by how greatly they varied in their ...
