A high efficient electrically small dual reflector antenna is designed and measured. A dielectric rod antenna(DRA) is used as the feed of the dual reflector antenna, due to its advantages of narrow ...

1. Andrew's 8.1 meter Ka-band SRT antenna. Sub-Reflector Tracking (SRT) Conventional ESA antennas use either step track or monopulse tracking techniques. At Ka-band frequencies, however, the antenna ...

The [IMSAI Guy] reflector is pretty small, but you can easily make bigger ones. Using PCB material for antennas isn’t anything new, either, but we still enjoyed this simple corner reflector build.

The Reflector Series line is described as “long-range, digital, outdoor HDTV” compatible. “These antennas use the latest technology to give users a powerful high gain antenna that is small enough to ...

L3Harris Technologies (NYSE:LHX) has introduced a new small satellite reflector antenna that will help decrease the size, weight and overall time to produce smallsats. Lighter and more compact ...

A 220 GHz electronically-scanning high-gain reflector antenna with a small-scale array feeder is presented in this paper. Multi-variables of the array feeder including the element spacing, defocused ...

ESA has unveiled a prototype 3D-printed radio antenna that is currently undergoing testing at the Compact Antenna Test Facility in Noordwijk, the Netherlands. It's the space agency's first 3D ...

The prototype antenna is the agency's first dual-reflector type to be 3D printed, according to its designer, Maarten van der Vorst. It incorporates the two reflectors and a corrugated feedhorn, and ...
