HIGHER ORDER MODE SUPPRESSION IN SINGLE AND DUAL BAND MICROSTRIP ANTENNAS

摘要

ABSTRACT Antenna structure for suppressing higher order modes� Embodiments herein provide an antenna structure for suppressing higher order modes. The antenna structure includes a signal transmission line and an antenna unit formed by etching a printed circuit board. Further, the antenna unit includes a signal feed-in point and a low pass filter incorporated within a patch of antenna unit. The low pass filter suppresses multiple resonances due to higher order modes generated in the patch. FIG.1A
