摘要

本文提出了一种用于2.4 GHz无线局域网(WLAN)应用的双圆极化槽天线。采用FR-4作为衬底对所提出的设计进行了仿真。在CST微波工作室中对天线的三个阶段进行了仿真。前两个天线，设计1-A和设计1-B包含一个具有不同馈线端口位置的单极化天线。x形结构以42.5度角位于贴片的中间。然后，设计双馈线端口天线B1，以产生双圆极化效果。设计2-A天线在2.4 GHz的回波损耗S11仿真结果和测量结果分别为- 21.511 dB和28.48 dB。端口1和端口2的轴比分别为0.63和1.12。最后，对仿真天线设计与实测天线设计进行了比较。

Dual Circular-Polarized Slot Antenna Design for Wireless MIMO System at 2.4 GHz

This work proposed a dual circular-polarized slot antenna for wireless local area network (WLAN) application at 2.4 GHz. The proposed design is simulated by using FR-4 as is substrates. In this work, three stages of antenna had been simulated in CST Microwave Studio. First two antenna, Design 1-A and Design 1-B is containing a single polarized antenna with different feedline port location. An X-shaped structure is located at the middle of the patch at angle of 42.5 degrees. Then, dual feedline port antenna, Design B1 are designed to create dual circular-polarized effect. The return loss S11 results at 2.4 GHz of Design 2-A antenna are - 21.511 dB and–28.48 dB for simulation results and measurement results, respectively. For axial ratio for Port 1 and Port 2 are 0.63 and 1.12, respectively. In the end, the simulation and measured antenna design are compared.
