Abstract

A compact multiple band-notch ultra-wide band (UWB) band-pass filter (BPF) with surface area of 18 x 12 mm² is introduced in this article. The proposed filter is a combination of novel symmetrically tapered elliptic rings (STER) and contiguous split ring resonators (SRR), with stepped impedance resonator (SIR) structure to realize the multi-band notch UWB pass band characteristics. In the proposed structure, band-notches are generated for interfering microwave bands such as, WiMAX, WLAN and X-band applications. These notches are achieved by optimizing structural parameters of SRR sections. The proposed filter is fabricated on RT/Duroid 5880 substrate with ε_r = 2.2 and thickness of 0.787 mm. The fabricated prototype is measured and a good agreement between simulated and measured results ensures suitability of the proposed filter for UWB applications.
