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 ...
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 ...
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 ...
To deliver the next generation of satellite applications, spacecraft are increasingly using phased arrays to combine multiple individual antenna elements to improve overall performance, increase gain, ...
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 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 ...
The properties of an amplifier can be tested along the lines of the following sketch. Typically, this technique would be applied to an RF or microwave amplifier, but this technique's additional ...
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 ...
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 ...
Satellite operators are using ever more complicated antennas to provide spot beams and increase satellite capacity. Engineers need a way to test these antennas on the ground. The European Space Agency ...
