摘要

在圆形微带天线的基础上，提出了一种新型2700扇形微带天线。此外，还提出了3000、3200和3400扇形微带天线的变体。在扇形贴片中引入了一个低于等效圆形贴片基模共振频率的新模。扇形贴片的高阶模态频率高于等效圆形贴片的频率。分析了扇形贴片在不同扇形角下前两模耦合所引起的带宽变化。3200扇区补丁实现500mhz的最优带宽(>50%)。所提出的天线在工作带宽上产生增益超过7 dBi的宽侧辐射方向图。

Broadband Proximity Fed Modified Circular Microstrip Antenna

A new 2700 sectoral micro strip antenna derived from circular micro strip antenna is proposed. Also its variations like, 3000, 3200 and 3400 sectoral micro strip antennas are proposed. In the proposed sectoral patch a new mode below the fundamental mode resonance frequency of the equivalent circular patch is introduced. The higher order mode frequencies of sectoral patch are higher than the frequencies of equivalent circular patch. The analysis for variation in bandwidth due to the coupling between the first two modes of the sectoral patch for different sectoral angle is presented. The optimum bandwidth of 500 MHz (>50%) is realized for 3200 sectoral patch. The proposed antenna yields broadside radiation pattern with gain of more than 7 dBi over the operating bandwidth.
