Abstract :
To address the continuing demand for high-performance advanced extremely high frequency (EHF) antennas for satellite communications, we developed a low-loss feedome for the axially displaced ellipse (ADE) reflector antenna for improved aperture efficiency. To examine the feasibility of the approach, a feedome is designed and a prototype is built in the frequency range of 43.545.5 GHz (Q-band). Simulation results using a linear feed horn correlate very well with experimental results employing an right-hand circularly polarized (RHCP) feed horn.
