A Hybrid Cubic Dielectric Loaded Tri-Band Antenna for Biomedical Applications

An eventual goal of this research article is to model a hybrid Tri-band dielectric resonator antenna (DRA) for biomedical applications. DRA’s are used in biomedical applications because of low metal losses and high gain. The resulting structure is fed via a microstrip feed line. A rectangular dielectric resonator antenna with a rectangular patch with a cross-shaped slot is designed to exhibit a tri-band. The suggested antenna has various gains of 2.62, 3.95, and 4.27 (in dBi) and could be operated over two ISM bands (2.45/5.8 GHz) and WiMAX (3.8 GHz). The proposed antenna performance is analyzed with body interaction as well as free space and is quite suitable for WBAN application which has met Specific Absorption Rate (SAR) standards. According to the antenna’s off-body analysis, it could be especially suitable for biomedical applications.
