Abstract

This paper presents investigations carried out at CNET in order to design a primary feed radiating a sectoral pattern (±70°). A rough synthesis method based on the equivalent radiating aperture of the feed is first used. Then it rigorously studies the electromagnetic performances of many related structures with a highly accurate analysis software based on the integral equation formulation. Lastly, it selects the final design for the feed horn and presents two breadboards and the associated measurements (normalized impedance and far field patterns) which show excellent agreement with simulation
