摘要

介绍了一种单馈多频紧凑矩形微带天线。在贴片的上边缘引入一个三角形的缝隙以降低谐振频率,在三角缝隙内生长一小块三角形的贴片以提高天线的增益带宽性能。与传统的方形贴片相比,天线尺寸减小了32.9%,最大带宽为160 MHz,回波损耗为- 34 dB,主要工作在WiMax 3.2-3.8 GHz频率范围内,带宽比为26.67%。

Triangular slot microstrip patch antenna for wireless communication
A single feed multi frequency compact rectangular microstrip antenna is presented in this paper. A triangular slot is introduced at the upper edge of the patch to reduce the resonant frequency A small piece of triangular patch is grown within the triangular slot to improve the gain bandwidth performance of the antenna. The antenna size has been reduced by 32.9% when compared to a conventional square patch with a maximum of 160 MHz bandwidth and −34 dB return loss Mainly it is developed to operate in the WiMax frequency range of 3.2–3.8 GHz with 26.67 % bandwidth ratio.
