Design and analysis of flexible cylindrical dielectric resonator antenna for body centric WiMAX and WLAN applications

This paper presents a flexible Dielectric Resonator Antenna made of polyester Resin which operates at 5.4 GHz for Wi-MAX and WLAN. Wearable material of indigo blue jeans is used as substrate for flexible DRA. The desired mode of HEM11 in cylindrical DRA is excited with the help of slot. Separate analysis of the DRA placed in free environment and close to human body is carried out. The performance of the antenna under both states: Free space and near body is investigated on the basis of antenna parameter. The proposed DRA has high gain of 5.41 dB and efficiency of 92%. The antenna has also high efficiency of 87% for near human body scenario.
