| Abstract: | According to the design request of ultra-wideband feed in Compact Antenna Test Range,a novel antenna com- posed of a tapered slot antenna and a TEM horn is investigated.The construct of this antenna is analyzed and the design method is given.Experiment results show that the VSWR of the antenna is less than 2 from 0.16GHz to 3.1GHz,and the antenna has the characteristics of low cross polarization,good direction patterns of E-and H-planes and small electrical size.It satisfies the re- quest d the CATR. |
