摘要
为扩大带宽的同时提高增益,设计了一种由四个矩形组合构成的微带贴片天线,该天线达到了在多波段的情况下兼具超高增益的电特性。天线工作在2.57-2.8 GHz,4.47-4.7 GHz,5.26-5.45 GHz,6.1-6.2 GHz,6.7-6.9GHz频带内,带内回波损耗均小于–10 d B,可应用于S波段、C波段、Wi MAX（2.3-3.5 GHz）和Wi Fi（5.25-5.35 GHz）频段,最高增益达到9.45 d B,比传统微带天线增益高了约5 d B。
In order to expand antenna bandwidth as well as improve the gain at the same time, a microstrip patch antenna consisting of four rectangular structures was designed. The antenna has multitude bands and high gains. The antenna is working in 2.57-2.8 GHz, 4.47-4.7 GHz, 5.26-5.45 GHz, 6.1-6.2 GHz, 6.7-6.9 GHz bands with all of return losses less than -10 dB. This type of antenna is suitable for S, C, WiMAX（2.3-3.5 GHz）, WiFi（5.25-5.35 GHz） bands. The antenna＇s maximum gain is 9.45 dB, which is about 5 dB higher than that of traditional microstrip antenna.
