摘要

本文对具有双分集多输入多输出(MIMO)结构和双带陷波特性的微带馈电低轮廓、紧凑型超宽带(UWB)单极天线进行了设计和分析。天线安装在低成本的FR-4衬底上，尺寸为38×60×1.6 mm3，相对介电常数为4.4。单个天线元件的原始形状为圆形，半径为11.5 mm，然后在贴片上去掉一个扇形(使其成为吃豆人形状的天线)，以提高阻抗带宽。该天线的阻抗带宽在2.9- 15ghz之间，回波损耗小于10db，隔离度小于- 17db。此外，该天线还可以抑制WiMAX (3.5 GHz中心频率)和WLAN (5.5 GHz中心频率)的干扰。

A compact printed UWB Pacman-shaped MIMO antenna with two frequency rejection bands

In this paper, the design and analysis of microstrip-fed low-profile, compact ultra-wideband (UWB) monopole antenna with its dual diversity multiple-input multiple-output (MIMO) configuration and two band-notches characteristics are carried out. The antenna is mounted on a low cost FR-4 substrate with dimensions of 38×60×1.6 mm3, and relative permittivity of 4.4. The original shape of the single antenna element is circular with radius of 11.5 mm, and then a sector is removed from the patch (making it a Pacman-shaped antenna) to improve the impedance bandwidth. The proposed antenna provides an impedance bandwidth between 2.9-15 GHz with better than 10 dB return loss and isolation less than -17 dB. Additionally, the antenna can reject the interferences from WiMAX (3.5 GHz center frequency) and WLAN (5.5 GHz center frequency).
