RESUMO
Abstract The design of a compact microstrip line-fed Ultra-wideband (UWB) monopole antenna with a notched band characteristic is presented in this paper. The rejection frequency band occurs around 5-6 GHz, which is appropriate for wireless local area network (WLAN) applications and is obtained by a split-ring resonator on the antenna ground plane. The proposed antenna is printed on FR4 substrate material with a dielectric constant of 4.4. The dimension of the proposed antenna is 24×16×0.8 mm3. Radiating patch has a combined geometry realized by a half-circular ring and half-square ring. To achieve a proper impedance matching and increased bandwidth with VSWR ≤ 2, the study made use of an L-shaped element which was connected to the ground plane; moreover, the researchers added a split-ring resonator onto the ground plane to obtain one notched band. The comparison of the proposed antenna performance with previously presented UWB monopole antennas, was performed by using Analytic Hierarchy Process method. A good agreement was observed between simulated and experimental results.
