Abstract

A rectangular dielectric resonator antenna (DRA) based on Barium Strontium Titanate-Cyclic Olefin Copolymer (BST-COC) composite for 2.4 GHz wrist application is designed and characterized. The dielectric properties of the composite with ~ 57 vol.% BST loading are characterized using microstrip ring resonator structures at 2.45 GHz frequency. The proposed DRA, fixed onto a reverse grounded FR4 laminate, has a very compact size of 19mm × 10mm × 5mm. The impact of the user's body proximity on the radiation performance of the antenna is studied experimentally. The percentage total efficiency and gain of the antenna deteriorated by about 8.5% and 2dB due to the proximity of the user's body. The proposed DRA showed better performance than that of resonant type of antennas when close to the user's body.
