Abstract
AbstractThis paper, proposes and analyzes, a novel and compact ultra-wideband (UWB) monopole antenna. The antenna is designed on a 1.6 mm thick, low-cost flame retardant-4 (FR-4) substrate. The overall footprint of the antenna is 20 × 14 mm2. Ansys High frequency structure simulator is employed to perform the simulations. The impedance bandwidth of the proposed antenna with S11 < –10 dB, is from 3.1 to 11.3 GHz, with a fractional bandwidth of 113%. For the whole UWB bandwidth, the average gain of the antenna is approximately 3 dB, and the average radiation efficiency is above 95%. The far-field radiation pattern of the antenna is dumbbell-shaped in E-plane and Omnidirectional in H-plane.KeywordsMonopole antennaUltra-wideband (UWB)Low costCompact
