Compact Isosceles Trapezoidal Dielectric Resonator Antenna for 2.4 GHz WLAN application

The paper presents an experimental study on a compact Isosceles Trapezoidal Dielectric Resonator Antenna (ITDRA) excited by microstrip line. It is observed that the DRA exhibits a 2∶1 VSWR bandwidth of ∼11.6 %, a gain of as high as 7.22 dBi and broad radiation patterns with good cross-polar levels that are consistent over the operating band. The antenna covers important application band of ISM: Bluetooth/ WLAN 2.4/Wibree ( 802.11 b/g/n )/ ZigBee. Details of the design along with experimental and simulation results are presented and discussed
