Wideband Shorted Bowtie Patch Antenna With Electric Dipole

Abstract

A wideband directional antenna composed of a shorted bowtie patch antenna and an electric dipole is presented. Through this composition, an equivalent magnetic dipole due to the shorted bowtie patch antenna and an electric dipole are excited together. Almost equal radiation pattern in the E- and H-planes is obtained. The proposed antenna has a wide impedance bandwidth, which is over 60% for SWR. < 2 ranging from 2.16-4.13 GHz.
