Abstract

In this paper a novel design of a printed ultra-wideband (UWB) circular slot antenna with 5.5 GHz band-notched characteristics is presented. A metallic-type split ring resonator (MTSRR) is inserted inside a circular slot underneath of a circular radiating patch at the opposite side of the dielectric substrate, to obtain the band-notched function. The proposed antenna satisfies the VSWR requirement of less than 2 in the frequency band between 2.85 and 10.78 GHz, which covers the UWB frequency band as approved by FCC, and maintains a band rejection capability in the frequency band of 5.30 to 5.80 GHz which defines higher range of frequency bands of the Wireless LAN services. The proposed antenna provides good gain flatness, high efficiency and nearly omni-directional field pattern over its whole frequency band excluding the rejected band. To enhance the comprehension of the antenna performance the input admittance of the proposed antenna is modelled as a SPICE compatible equivalent circuit using Vector Fitting technique, and the validity of the modelling method is verified.
