| 摘 要： | 方形螺旋天线结构简单、频带范围宽,是一类性能优良的天线,但在变成定向辐射后其带宽会大大减小。本文研究了一种采用渐变介质的新型定向双臂方形螺旋天线,仿真结果表明,其带宽得到明显增加,可以成功应用于PCS及WLAN等通信系统中。

| Abstract: | The square spiral antennas have many outstanding merits such that its structure is simple and its bandwidth is wide.But if it changes to a directional antenna, then its bandwidth will decrease dramatically.In this paper,we present a new kind of two-arm square spiral antenna with tapered substrate.The simulated results show that we can expand its bandwidth obviously in this way,and this antenna can be applied in PCS or WLAN systems successfully. |
