摘要

本文提出了一种新型多波段微带天线的设计方案。该天线的辐射元件由矩形环形微带和折叠弯曲臂组成,用于高模激励、频率选择和控制。为了获得天线物理参数的最优值,进行了多次优化。利用CST MICROWAVE STUDIO™2010对该天线进行了仿真。仿真结果表明,该天线存在2.35GHz、2.82GHz、5.1GHz和5.85GHz四个谐振频率,具有工业、科学和医疗(ISM)、闭路电视(CCTV)和无线局域网(wlan)系统应用的三频段频率天线的特性。该天线尺寸紧凑,为1.6×28×30 mm3,在所有工作频率下都具有合理的增益,显示出相当好的全向辐射方向图。

Multiband CPW-fed rectangular ring microstrip antenna design for wireless communications
This paper presents a new design of multiband microstrip antenna. The radiating elements in this antenna are composed of rectangular ring microstrip and a folded meandered arm used for higher mode excitation, frequency selection and control. Several optimizations are performed to attain the optimum values of the antenna physical parameters. The simulation of this antenna has been carried out using CST MICROWAVE STUDIO™ 2010. The simulation results show the presence of four resonant frequencies (2.35GHz, 2.82GHz, 5.1GHz, and 5.85GHz) and having the behavior of triple band frequency antenna for Industrial, Scientific and Medical (ISM), Closed Circuit Television (CCTV), and Wireless Local Area Networks (WLANs) system applications. The antenna has a compact dimension of 1.6×28×30 mm3 and shows fairly good omnidirectional radiation patterns with reasonable gains at all operating frequencies.
