Rectangular Dielectric Resonator Antenna (RDRA) for anti-collision short range radar (SRR) application

This paper presents the design of Rectangular Dielectric Resonator Antenna (RDRA) feed by a micro-strip line for anti-collision radar SRR application at 24 GHz. The proposed RDRA operates at a frequency of 24 GHz with a high dielectric constant of 41. The simulated RDRA has a high radiation efficiency (88.4 %). The return loss, radiation pattern and gain of the proposed antenna are evaluated. The simulation process was carried out using Computer Simulation Technology (CST) Microwave Studio.
