【摘要】 微带天线的窄带特性是限制其广泛应用的重要原因之一,如何展宽微带天线的带宽一直受到人们的广泛关注。本文提出了一种新颖的小型宽带圆极化的微带天线,其形状像"8",通过CST对提出的天线建模并仿真,通过优化该模型可使其带宽达到1.053GHz,在工作范围内某一频点上增益高达9.2dB,该天线可用于卫星接收以及手机天线。更多还原

【Abstract】 The narrow-band characteristics of microstrip antenna badly restrict its extensive applications, how to broaden the bandwidth of microstrip antennas has been hot subject for people. This paper presents a novel small broadband microstrip antenna of circular polarization, "8" shape. The proposed antenna is modeled and simulated by virtue of CST, through optimization, the bandwidth can reach 1.053GHz, gain is up to 9.2dB within its work frequency. The antenna can be used for satellite reception, as well as phone antennas.更多还原
