Abstract

Cassegrain Reflector Antenna Design consists of various effects caused by blockage and its effect on overall performance. The design for minimum blockage condition results in geometry that offers lower amount of blockage and increased spillover past the subreflector. To avoid this, optimized design of the antenna results in geometry that offers lower amount of spillover past the edges of the main reflector and increases some percentage of blockage. The design of feed elements for Cassegrain antennas is considered in the following section. It includes the design of conical corrugated horn antenna having throat section. Throat section is used for the purpose of achieving match between input waveguide and horn thereby maintaining low VSWR. The Scalar Horns are used to obtain identical performance in both the principal planes. The dual reflector design is simulated on the ‘Induced Current Analysis of Reflector Antenna’ software. Ansoft HFSS is used to obtain the radiation characteristics of the Corrugated Horn.
