NON-WAVEGUIDE METHODS OF MILLIMETER WAVE, TRANSMISSION
Abstract
The feasibility of transmission between two closely spaced antennae was established with transmission loss lower than that of rectangular waveguide. Defocus of antenna feeds has improved performance. Transmission around corners at no loss was demonstrated. The use of a dielectric sheet as a power divider was proved effective. A circular polarization duplexer was developed. A pair of dielectric prisms was used very effectively as an adjustable bi-directional coupler, as an attenuator and as a duplexer. The effect of reflections at prism surfaces was analyzed and an effective means of controlling them was devised. The effect of surface distortions on antenna performance was analyzed and a computer program was written to compute for zone field under these conditions. Application was made to an idealized symmetrical case. A high precision antenna pattern range was set up to evaluate experimentally the patterns from distorted antennae. Only preliminary measurements were made.
