摘要
研究双频共口径双馈天线的设计方法,并用ANSFOT分析软件对天线电特性进行仿真分析,依据此分析结果,研制天线实物样机。样机电参数测量结果表明,双馈口天线两端口的隔离度达到了35.4 dB,方向图全向不圆度小于2 dB,增益大于5 dB,从而证明了设计方法的有效性。
The design of antenna for dual -band co -aperture in dual -feed is presented. The feeding network of the antenna is Simulated by commercial EDA software ANSOFT. Then the sample is made and measured. The measured results show that the antenna in dual- feed is of isolation is better than 35 dB between the ports,the non -circularities of the H -plane omnidireetional pattern that is less than 2 dB,the gain is better than 5 dB,and this design method is valid.
