摘要：This paper demonstrates a novel multi band reject filter using complimentary split ring resonators .Here the proposed antenna was designed using Ansys HFSS software. This multiband reject filter attenuate frequencies at 2.67 GHz, 3.5 GHz, 6.6 GHz, 9.1 GHz and 11.3 GHz. This multiband reject filter is used to enhance the bandwidth and improve the return loss with the help of complimentary split ring resonators on the ground plane. The SRR is a common structure to implement meta-material properties. The SRR consists of concentric metallic plates etched on a dielectric surface which is used to increase the frequency attenuation characteristic and in turn placing these SRR at desired position led to increase of bandwidth from 0.1232 to 0.1561. The band reject filter is prone to frequency distortions which are removed by the complimentary split ring resonators. The split ring that was taken in the paper shown a good increase in the bandwidth but in order to increase the bandwidth more we opted to take an another complimentary split ring resonator over the original split, which increased the bandwidth more. The proposed band stop filter antenna characteristics are used for the medical application such as electrocardiogram.
