Abstract

A broadband folded patch feed antenna for ultrawideband (UWB) application is proposed and designed. The antenna consists of a folded patch feed and a shorting wall attached to E and H shaped stack patch. Bandwidth broadening is achieved by an H shaped patch fed by a folded patch feed and the size reduction is realized through the use of shorting wall. Electromagnetic coupling in between E and H shaped stack patch further enhance the impedance bandwidth in this design. The proposed antenna has a small electrical size of 19 times 15 times 10 mm³ and an impedance bandwidth of 102.36% ranging from 3.42 to 10.59 GHz. Relatively stable radiation patterns with gain greater than 4.5 dBi is obtained over the entire bandwidth.
