【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。更多还原

【Abstract】 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 omnidirectional pattern that is less than 2 dB,the gain is better than 5 dB,and this design method is valid.更多还原
