Survey of Embedding MSRRs Structure on Compactness and Bandwidth Operation of UWB Antenna

The effect of embedding regular and modified multiple split-ring resonators on the ultra-wideband antenna is proposed and studied. By embedding the structures on the compact UWB antenna a novel method for enhancing the performance of the antenna in the desired frequencies is realized. The proposed configurations are useful for enhancing the banding by combining several resonant modes. The antenna in special conditions, in which the MSRR structures rings width are minimized and modified to avoid of notching shows good impedance matching in desired frequencies.
