Abstract :
A new design of TEM wideband horn feed with four orthogonal ridges is presented, resulting in better VSWR and gain antenna for 6m-diameter reflector antenna. By tapering the ridges, it is possible to extend the operating frequency band while decreasing the size of feed. The proposed wideband feed with dual linearly polarization and compact size in a shared aperture takes the features of constant phase center, high efficiency etc. The feed is simulated with Ansoft HFSS. Design consideration, the simulated and measured VSWR of the constructed feed over the frequency band f0 ± Δf are presented and discussed which the Δf=0.34 f0.
