This paper will present a novel wide-band double-ridged standard horn antenna at 0.5~6GHz with the software named Ansoft HFSS, which is mainly used for far-field antenna measurement system. A simulation model of wide-band double-ridged horn antenna and the detailed design of each part of the structure will be given. With optimization in HFSS, the results show that the VSWR in the whole frequency band is below 2.4 and average gain larger than 6 dB. Finally, results of the measurement for VSWR, gain and radiation pattern are presented and discussed, which indicates that the built prototype is consistent with the design goals very well.
