Abstract
Vector ElectroMagnetics, LLC and The Ohio State University ElectroScience Laboratory propose to adapt design modifications to existing AFSCN ground site SATCOM antenna systems in order to reduce radio frequency interference (RFI) from various sources in L and S bands. The proposed modifications will reduce side and back lobes in the antenna radiation pattern by at least 10 dB as well as achieve a dynamically controllable main-beam beam-width. Specifically, two approaches will be pursued: 1) A tapered impedance edge treatment will be applied to the perimeter of the main reflector in order to reduce the diffracted energy that gives rise to high side and back lobes, and 2) The existing conventional feed antenna will be replaced by an electronically controlled array capable of dynamically adjusting the aperture distribution and therefore the overall radiation pattern of the AFNSC antenna system. The proposed designs will be: 1) analyzed using modern CEM tools, and 2) verified via fabrication and measurement of test articles.
