Abstract

A simple, very small equilateral triangular microstrip patch antenna (ETMPA) having sides 15mm with an I-slot of optimum length and position on the radiating patch has been designed to generate a wide frequency band. Impedance bandwidth generated by the antenna is 610MHz 10.8%, (5.34-5.95GHz) for (S11 ≤ −10 dB) having broadside radiation pattern with peak gain of 1.66dB. The designed antenna covers Weather Radar application band(5.35-5.45)GHz, Radiolocation and Military application band (5.47-5.57) GHz, Maritime Radar application band (5.57-5.65)GHz, WLAN-Europe(5.470-5.725)GHz, Wi-Fi 5.8(5.725– 5.850)GHz and Dedicated Short-Range Communications(DSRC) band (5.850-5.925)GHz. FR4 material having relative permittivity(εr) 4.4 and loss tangent(tanδ) 0.02 has been used as dielectric substrate and thin copper sheet used as radiating patch and ground in the designed antenna. Prior to physical fabrication and measurement, the proposed antenna has been designed and analyzed using commercial High Frequency Structural Simulator (HFSS) ver13 software. Good matching has been observed between measured and simulated results.

一个简单的小型化宽带等边三角形微带贴片天线

设计了一种简单的、非常小的等边三角形微带贴片天线(ETMPA)，其边长为15mm，在辐射贴片上具有最佳长度和位置的i -槽，以产生宽频带。天线产生的阻抗带宽为610MHz 10.8%， (5.34-5.95GHz)， (S11≤- 10 dB)具有宽边辐射方向图，峰值增益为1.66dB。设计的天线涵盖气象雷达应用频段(5.35-5.45)GHz、无线电定位和军事应用频段(5.47-5.57)GHz、海事雷达应用频段(5.57-5.65)GHz、wlan -欧洲(5.470-5.725)GHz、Wi-Fi 5.8(5.725 - 5.850)GHz和专用短程通信(DSRC)频段(5.850-5.925)GHz。设计的天线采用相对介电常数εr为4.4、损耗正切值tanδ为0.02的FR4材料作为介质衬底，薄铜片作为辐射贴片和地。在物理制造和测量之前，已经使用商用高频结构模拟器(HFSS) ver13软件对所提出的天线进行了设计和分析。实测结果与模拟结果吻合良好。
