M-Shaped Dielectric Resonator Antenna for WLAN Applications

In this paper, a new dielectric resonator antenna (DRA) is designed for WLAN applications, where a simple M shaped dielectric resonator (DR) is excited by a conformal patch connected to a microstrip line. The simulation process was done by using computer simulation Technology (CST) Microwave studio suite 2010.The simulated results show that the proposed DRA achieves an impedance bandwidth of about 31.32% for VSWR ≤ 2, covering a frequency range from 4.63 GHz to 6.35 GHz. The antenna also provides a gain range of 5.64-7.34 dB across the operating bandwidth. The proposed antenna is suitable for wireless local area networks (WLAN 5.15-5.30GHz) (IEEE 802.11a). It has also application in high performance radio LAN (HIPERLAN) which operates across 5.15 to 5.30 GHz.
