Ka Band Cassegrain Monopulse Antenna Fed by Tapered Rod Antennas

摘要：

A Ka band Cassegrain monopulse antenna has been designed and measured.The tapered rod antennas are used as the feeds of the Cassegrain antenna because their blockage is small and their bandwidths are very wide.The measurements show that the gain of sum pattern is 28dBi,the sidelobe levels of the sum pattern are less -15dB,the null depths of the difference pattern are less then -25dB and the bandwidth of VSWR<2 is more than 6.5GHz.
