Metamaterial Inspired Multiband Antenna Using SRR

This article presents metamaterial inspired Multiband Antenna consisting of six split rings. The proposed antenna is 40x40x0.8 mm
³
CPW-fed multiband antenna operating at seven resonances within the frequency range of 112 GHz. The advantages of reduced dispersion and uniplanar design are used to adopt the CPW feeding approach. Miniaturization and multiband are achieved using the suggested SRR configuration. In this work, SRR is a six-time repetitive representation of the ring structure that uses 0.5mm wider rings. The antenna is implemented on a low cost FR4 substrate and is measured using anechoic chamber. The measured performance parameters of the designed antenna are in close proximity of the simulated ones.
