A high gain Novel Dielectric Resonator Antenna (NDRA) for anti-collision short range radar (SRR) application

This paper presents the design of Novel Dielectric Resonator Antenna (NDRA) feed by a micro-strip line for anti-collision radar SRR application at 24 GHz. The proposed NDRA operates at a frequency of 24 GHz with a dielectric constant of 18. The simulated NDRA has a high gain (12.24 dB) and a high radiation efficiency (94 %). 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.
