摘要

本文提出了一种新型宽带共形天线。天线为宽带定向共形叉形天线。采用锥形缝隙天线和偶极子阵列相结合的方法获得定向辐射方向图。偶极子元素形成像叉一样，具有半环形结构。因此，对数周期天线的概念不是使用线偶极子，而是在拟议的天线中使用三个叉形偶极子元件。所提出的径向圆柱共形天线工作在3.5 ~ 4.1 GHz，阻抗带宽为600 MHz。在工作频率范围内，径向圆柱共形天线的增益约为4.7 ~ 5.6 dBi。3.3 GHz和3.5 GHz半功率波束宽度HPBW在h面分别为122°和116°，在e面分别为56°和57°。提出的圆柱形天线是一种适用于WiMAX应用的合理天线。

Design of a Wideband Periodic Cylindrical Conformal Fork shaped Antenna for WiMAX Application

A novel shape of wideband conformal antenna is presented in this article. The antenna is a wideband directional conformal fork shaped antenna. A combination of the concept of tapered slot antenna and dipole arrays are used to obtain directional radiation pattern. The dipole element is formed like a fork and has a semi-annular ring structure. As a result, instead of using a wire dipole, the concept of a log periodic antenna, uses three fork-shaped dipole elements in the proposed antenna. The proposed radial cylindrical conformal antenna is operating from 3.5 to 4.1 GHz achieves an impedance bandwidth of 600 MHz. The gain of the proposed radial cylindrical conformal antenna is around 4.7 to 5.6 dBi within the operating frequency.The halfpower beamwidth HPBW at 3.3 and 3.5 GHz are 122° and 116° in the H-plane and at E-plane are 56° and 57° respectively. The proposed cylindrical antenna is a reasonable antenna for WiMAX applications.
