Candidate coatings for a new space antenna undergoing testing at ESA's technical heart in the Netherlands. "Protective coatings safeguard antennas against temperature extremes or other environmental ...

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 ...

ESA's newest radio-frequency test facility allows direct measurement of antenna systems in the very vacuum conditions and thermal extremes they will work in, including the chill of deep space. It will ...

One very successful trick I use to simulate radiated immunity on the bench is to run an RF generator into an H-field (loop) probe. The best level seems to be +15 to +20 dBm. This will generate an ...

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 ...

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 ...

It is often necessary to provide some type of shielding in order to perform RF/wireless testing with an acceptable amount of external noise. It is also often necessary to perform testing where the ...

RF antennas serve as an important link between user terminals and communication base station equipment. Radio waves, which are central to this process, are electromagnetic waves that propagate at a ...

Implementation of the 5G radio frequency (RF) standard is increasing rapidly [1]. Over the past four to six quarters, there has been an increased focus on publications and products that have been ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...
