Circular SRR Shaped UWB Antenna with WiMAX Band Notch Characteristics

Abstract

A Compact ultra-wideband microstrip patch antenna with single notch characteristics is proposed in this paper. The proposed antenna comprises of a split ring resonator (SRR) and an open loop rectangular resonator (OLRR). The split ring resonator in this paper plays a dual role, it acts as a radiating patch and also as a band rejecter to eliminate the entire worldwide interoperability for microwave access (WiMAX) covers 3.3 GHz – 3.6 GHz band. OLRR is used for the suppression of the harmonic frequency band notch. The compact size of the antenna is $\mathbf{36}\times \mathbf{30}\ \mathbf{mm}^{2}$.
