Honeycomb shaped fractal antenna with dual notch characteristic for UWB applications

Abstract

The paper presents a feasible way to construct the honeycomb structured microstrip antenna for UWB (Ultra-Wideband) applications with dual notch characteristics. The antenna is designed based on the concept of the initial stage of honeycomb nest construction and defected ground structure (DGS) with dual notch for UWB applications. The two notches for WiMAX (3.5GHz center frequency) and WLAN (5.5 GHz center frequency) are introduced by etching two asymmetrical quarter wavelength slots in the ground. The compact antenna of size 12 x 20 mm 2 with simple geometry achieves very wide bandwidth of 3.1-13.8 GHz (Covers UWB and higher frequency band) with dual notch characteristic.

“…Various methods have been proposed to achieve band-notch characteristics [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The most common technique is to cut a slot on the patch or the feed line and the ground plane.…”
