Abstract
This paper describes the simple design of a dielectric resonator antenna for 2.4 GHz using a regular cubic resonator for biomedical applications. Dielectric resonator antennas (DRAs) are used at microwave and millimeter frequencies and consist of materials having a high dielectric constant that have high gain and directivity. The resonator is placed upon a copper-grounded fire-resistant substrate. The selected dielectric resonator has a resonant frequency fr = 2.4 GHz and dielectric constant εr = 9.8. Computer Simulation Technology (CST) Microwave Studio was used to perform the simulation and analysis. The gain of the proposed antenna is 1.508 dBi and the directivity is 2.121 dBi.
