Abstract

Antennas based on dielectric rod waveguide made of GaAs and fused sapphire cut along its optical axis inserted in the end of a standard WR-10 metal waveguide are investigated with computer simulations and experiments in the W band. The radiation pattern is found to be similar to that of the open metal waveguide end, but less frequency-dependent beamwidth and input match: measured return loss is more than 25 dB.
