Bidirectional CPW Fed Quad-Band DRA for WLAN/WiMAX Applications

Due to the size constraint, antennas with compact are required that can support multibands single radiating element. Dielectric resonator antenna (DRA) multiple modes good efficiency and gain using In this paper, a quad-band DRA is proposed for WLAN/WiMAX bands CPW feed. Out of four bands, WLAN (2.37-2.55) GHz, (5.15-5.35) (5.6-5.83) GHz achieved by excitation fundamental higher-order whereas WiMAX (3.58-3.72) band dielectric loading DR. makes it possible operate at desired frequency band. partial ground plane coplanar waveguide (CPW) feed radiation pattern bidirectional. The design efficient in terms efficiency. Simulated measured results show be suitable candidate applications.
