In this article, a compact octagonal-shaped UWB antenna with Minkowski fractal-shaped notch and a dual C-shaped notch is presented. The Minkowski fractal helps to obtain band rejection at WiMAX (3.4-3.7 GHz) band, whereas dual C-shaped notch on either side of feed line provides the band rejection at WLAN (5.15-5.825 GHz) band.
Moreover, a rectangular slot is also inserted in the ground plane, which helps to obtain the desired UWB bandwidth. The proposed antenna has the compact size of 26 x 16.5 mm(2). The proposed antenna shows proper impedance matching, stable radiation pattern with good antenna gain ;(2-5 dBi) over the entire UWB frequency range.
