摘要

本文设计了一种中心频率为2.5GHz的用于WiMAX应用的微带矩形贴片天线。设计了基于四分之一波阻抗匹配技术的4 × 1 (4x1)贴片阵列微带馈线矩形天线阵列，并利用CST微波环境软件进行了仿真。在回波损耗、驻波比(VSWR)、带宽、指向性、辐射方向图和增益等方面与单贴片矩形天线进行了比较。然后在介电常数为4.9、厚度为1.6mm的FR-4衬底上制作阵列天线。利用矢量网络分析仪(VNA)在实验室对阵列天线进行了测量，结果与阵列天线的仿真性能吻合较好。

Microstrip Rectangular 4x1 Patch Array Antenna at 2.5GHz for WiMax Application

This paper presents the design of microstrip rectangular patch antenna with center frequency at 2.5GHz for WiMAX application. The array of four by one (4x1) patch array microstrip rectangular antenna with microstrip line feeding based on quarter wave impedance matching technique was designed and simulated using Computer Simulation Tool (CST) Microwave Environment software. The performance of the designed antenna was than compared with the single patch rectangle antenna in term of return loss, Voltage Standing Wave Ratio (VSWR), bandwidth, directivity, radiation pattern and gain. The array antenna was then fabricated on the substrate type FR-4 with dielectric constant of 4.9 and thickness of 1.6mm respectively. The array antenna was measured in the laboratory using Vector Network Analyzer (VNA) and the results show good agreement with the array antenna simulated performances.
