Abstract

A wideband double-ridged pyramidal horn has been designed and fabricated for a phase calibration system, which is being developed for VLBI (Very Long Baseline Interferometry) multi-band receiver system. The operating frequency band of the horn covers across 22 and 129 GHz. Double-ridged waveguide structure has been employed for the ultra-wideband application. Measured return loss is better than 9.4 dB and measurements of radiation patterns are compared with simulations from 22 to 110 GHz.
