Abstract
A folded patch fed compact UWB antenna is proposed and designed. The UWB band is obtained by E-H shaped stacked with H shaped patch, fed with a folded patch feed and the size reduction is realized through the use of shorting wall. The antenna has a compact structure, and the total size is 15 by 14mm by 10mm. A relative impedance bandwidth of 100% (from 3.46 to 10.36 GHz) is achieved. Also, the antenna is able to achieve the stable radiation performance with gain greater than 4 dBi across the UWB band.
