摘要

本文提出了一种具有带宽增强和谐波抑制功能的小型微带贴片天线。辐射贴片由非辐射四分之一波长谐振器的微带短段耦合和激发。由于耦合四分之一波长谐振器工作在接近辐射贴片中心频率的另一个谐振频率上，因此有效地增强了带宽。该天线获得了6.1%的带宽(4.73 ~ 5.03GHz)，在带宽范围内具有满意的辐射性能，并且明显抑制了有害的高阶辐射模式。此外，单四分之一波长谐振器结构紧凑、简单，使其激发贴片更灵活，更易于排列。

A compact microstrip patch antenna with bandwidth enhancement

In this paper, a compact microstrip patch antenna with bandwidth enhancement and harmonic suppression has been presented. The radiating patch is coupled and excited by a microstrip stub which is a non-radiating quarter wavelength resonator. Because the coupling quarter wavelength resonator operates at another resonant frequency close to center frequency of the radiating patch, the bandwidth is enhanced effectively. The proposed antenna acquires 6.1% bandwidth (from 4.73 to 5.03GHz), with a satisfactory radiation performance within the bandwidth and the harmful higher order radiating modes have been obviously suppressed. Moreover, the single quarter wavelength resonator makes it more flexible to excite patch and easier to be arranged in arrays for its compact and simple structure.
