- Abstract
This paper presents a candidate ultra wideband antenna for Ku-band wireless communications applications, analyzed and optimized by the finite element method (FEM). This three-dimensional modeling was realized and compared with published antennas for validate the performances of the proposed antenna. Its design is based on the insertion of several symmetrical slots of different sizes on the ground plane of a mono-layer patch antenna to overcome the main limitation of the narrow bandwidth of patch antennas. The proposed antenna, made on an FR-4 epoxy mono-layer substrate with a defected ground plane (dielectric constant εr = 4,4, loss tangent tan δ= 0,02 and thickness hs = 1.6 mm). The simulated numerical results obtained are very satisfying; Bandwidth = 10.48 GHz from f1 = 9.34 GHz to f2 = 19.82 GHz, S11 = -34.17 dB, Voltage StationaryWave Ratio VSWR = 1.04, Gain = 6.27 dB.
