摘要

本文提出了一种用于无线通信系统的改进地平面双宽带高增益圆形微带天线。建议天线的整体尺寸为50 x 40 x 1.6 mm3。辐射元件由圆形贴片组成，该贴片由印刷在FR4环氧基板上的微带馈线激发。接平面位于基板的另一侧，具有矩形环形形状，以增强天线的峰值增益。所提出的天线具有两个宽的分数带宽(基于?-10 dB)分别为61.1% (2.0 - 3.8 GHz，以2.88 GHz为中心)和53.37% (5.48 - 9.6 GHz，以7.44 GHz为中心)。在8.76 GHz时实现的测量峰值增益为8.25 dBi。测量的阻抗带宽和增益足以满足所有无线系统的商用频段，如4G LTE band-40、蓝牙、Wi-Fi、WLAN、WiMAX、C-band和Xband。对测量结果进行了实验测试，并与仿真结果进行了验证。他们之间达成了合理的协议。

Dual wideband and high gain microstrip antenna for wireless system

In this paper dual wideband high gain circular shaped microstrip antenna with modified ground plane is presented for wireless communication systems. The overall dimension of the proposed antenna is 50 x 40 x 1.6 mm3. The radiating element consists of circular shaped patch which is excited by microstrip feed-line printed on FR4 epoxy substrate. The ground plane is on the other side of the substrate having a rectangular ring shape to enhance the peak gain of the antenna. The proposed antenna exhibits two wide fractional bandwidths (based on ? -10 dB) of 61.1% (ranging from 2.0 to 3.8 GHz, centred at 2.88 GHz) and 53.37% (ranging from 5.48 to 9.6 GHz, centred at 7.44 GHz). The measured peak gain achieved is 8.25 dBi at 8.76 GHz. The measured impedance bandwidth and gain suffice all the commercial bands of wireless systems such as 4G LTE band-40, Bluetooth, Wi-Fi, WLAN, WiMAX, C-band, and Xband. The measured results are experimentally tested and verified with simulated results. A reasonable agreement is found between them.
