摘要

提出了一种新型的、紧凑的、具有双极化特性的三波段y形单极天线,用于WLAN和WiMAX应用。天线主要包括在中心有两个矩形槽的部分地,微带馈电的y形辐射贴片,该辐射贴片由两个不等的单极子臂组成,中间嵌入一个单极子。天线结构极其简单,占用空间小。实验数据表明,该天线可以提供371 MHz(以2.4 GHz为中心)、50 MHz(以3.5 GHz为中心)和2790 MHz(以5.8 GHz为中心)三个独立的阻抗带宽。此外,天线在工作频段(2.365 ~ 2.57 GHz和5.73 ~ 6.07 GHz)内呈圆极化。此外,该天线在三个工作频段上显示出单极态辐射方向图和稳定的天线增益,使其适合WLAN和WiMAX的实际应用。

A Triple-Band Monopole Antenna with Dual-Polarization Characteristics
A novel and compact triple-band Y-shaped monopole antenna with dual polarization characteristics for WLAN and WiMAX applications is proposed. The antenna mainly comprises a partial ground with two rectangle slots in the center, a microstrip-fed Y-shaped radiating patch that consists of two unequal monopole arms with a middle monopole embedded. The antenna structure is extremely simple and occupies small space. Experimental datas show that the antenna can provide three separate impedance bandwidths of 371 MHz (centered at 2.4 GHz), 50 MHz (centered at 3.5 GHz) and 2790 MHz (centered at 5.8 GHz). In addition, the antenna is circularly polarized in the operating bands (2.365-2.57 GHz and 5.73-6.07 GHz). Furthermore, the antenna shows monopole-like radiation patterns and stable antenna gains across the three operating bands, making it suitable for WLAN and WiMAX practical applications.
