The Design of UWB Double-Ridge Horn Antenna

To reduce the difficulty and cost of measurement, this paper proposes an ultra-wideband (UWB) double-ridge horn antenna, whose operating frequency is 6GHz-67GHz. The measured results of VSWR are less than 2.5, the gain are 13dB Typ. and the cross polarization isolation are 30dB Typ. This horn antenna has been widely used in measured fields and appears good performance.
