Metamaterial-inspired printed UWB antenna for short range RADAR applications

This research article presents a novel design of printed antenna for 24 GHz ultra-wideband (UWB) applications. This research develops an antenna having dimension of 5 x 6 x 0.8 mm(3) which operates from 24 to 30 GHz. This is achieved using techniques such as truncation of patch edges and inclusion of complementary split ring resonator metamaterial (MTM). This antenna can be used for short range RADAR application at 24 GHz UWB for automotive appliances. This article includes the detailed investigations such as surface current distribution on antenna, far field patterns, gain, group delay and radiation efficiency over frequency, as well as measurement details. Simulation and measurement data on return loss have shown good equality which proves the feasibility of the proposed antenna.
