Abstract
AbstractThe cross‐polarization, signal attenuation and boresight shift for a number of dielectric space frame (DSF) radomes have been investigated using the induced field ratio method. It is shown that DSF radomes produce substantially less cross‐polarization than their metal counterparts. It is concluded that in view of INTELSAT's specification of 30.7 dB cross‐polar discrimination within an antenna's tracking beamwidth for frequency re‐use communication system antennas, DSF radomes, in particular those considered, would not yield appreciable system degradation. The general method presented is extendable to other radomes structures provided that connectivity information is available.
