Abstract

A single layer, single feed, multi frequency, compact rectangular micro strip patch antenna is proposed. Resonant frequency has been reduced drastically by cutting unequal rectangular slots at the edge of the patch along with two tiny circular slots created inside the patch to improve return loss. Antenna size has been reduced by 64% with an increased frequency ratio (the ratio of second or higher resonant frequency to the first resonant frequency).

一种新颖紧凑的多频微带天线

提出了一种单层、单馈源、多频、紧凑的矩形微带贴片天线。通过在贴片边缘切割不均匀的矩形槽以及在贴片内部创建两个微小的圆形槽来改善回波损耗，从而大大降低了谐振频率。随着频率比(第二或更高谐振频率与第一谐振频率之比)的增加，天线尺寸减小了64%。
