Design and Analysis of Dielectric Resonator Antenna for Wearable Applications

This paper propounds the design of a wearable wideband antenna loaded with a DRA (Dielectric Resonator Antenna) to achieve greater bandwidth characteristics. The wearable wideband antenna is designed on a jean substrate of thickness 0.6mm which has a ε
_r
(dielectric constant)value of 1.73. The proposed antenna is made to operate in the wideband range of 2.7GHz to 15GHz. The radiator is modified to achieve more efficient return loss. The jean substrate chosen is ideal for textile and on body wearable applications. The DRA is a ceramic alumina material of cylindrical shape loaded on to the antenna to reduce the specific absorption rate and the radiation pattern maintains a stable omnidirectional characteristics.
