Antenna concept selection
Abstract
Most essential antenna concepts based on RF configuration with about 3m diameter and 12GHz operation frequency including hybrid system with double rib reflector, hybrid system with one mesh reflector, expandable truss antenna, umbrella type antenna with one mesh reflector, double rib umbrella antenna, and flexible rib antenna with one mesh reflector, as well as their main properties, are used as the basis for an evaluation. Mechanical, material and thermal criteria, manufacturing and development criteria, and reliability were emphasized. It is shown that the optimum concept is the hybrid system with a double grid reflector which has the following main features; high efficiency, low side lobe level, low weight, high surface accuracy, low thermal distortions, and degraded mode capability.
