Abstract

In this paper, a planar bow-tie slot antenna with coplanar waveguide fed for tri-band i.e. WIMAX, C and X band wireless communication applications is proposed. This antenna has been designed to meet the prerequisite of multiple resonant frequencies by setting up the proper dimensions of the bow-tie arm slots and feed line cutout slots. The dimensions corresponds to the tri-band resonant frequencies, are obtained by engraving slots of distinct length and width above the ground plane. The antenna is fed by 50Ω coplanar waveguide feed line. Physical size of the proposed antenna is 30×60 mm2 designed on thick substrate. The copper cladding ArlonCuClad217(tm) woven fiberglass laminate material with dielectric loss tangent 0.0009 and relative permittivity 2.17 is used. The gain, impedance bandwidths, return loss, and VSWR of proposed antenna has been analyzed and discussed. Moreover, the extensive parametric study has been carried out with the dimensions of feed line cutout. The simulation results have shown that the designed prototype of an antenna exhibits the peak realized gain of 6.9dBi and average gain of 2.3dBi.The proposed antenna has three operating bands, which are suitable for WIMAX, C-band and X-band applications.

一个紧凑的共面波导馈电领结槽天线，用于WIMAX, C和X波段应用

本文提出了一种共面波导馈电的平面领结槽天线，用于三波段即WIMAX、C和X波段无线通信。该天线通过合理设置领结臂槽和馈线切断槽的尺寸来满足多谐振频率的前提。尺寸对应于三波段谐振频率，是通过在地平面上雕刻不同长度和宽度的槽得到的。天线由50Ω共面波导馈线馈电。该天线的物理尺寸为30×60 mm2，设计在厚基板上。采用镀铜ArlonCuClad217(tm)编织玻璃纤维层压材料，介质损耗正切为0.0009，相对介电常数为2.17。对该天线的增益、阻抗带宽、回波损耗和驻波比进行了分析和讨论。此外，还对进给线切口的尺寸进行了广泛的参数化研究。仿真结果表明，设计的天线样机的峰值实现增益为6.9dBi，平均增益为2.3dBi。该天线具有三个工作频段，分别适用于WIMAX、c波段和x波段应用。
