Abstract

In this paper, a heuristic search method called Gravitational Search Algorithm (GSA) is proposed to design Ultra-wideband antennas (UWB) with irregular shape radiators. To measure the algorithm efficiency in practical antennas design, the results are compared with those obtained using the Central Force Optimization (CFO) technique. The optimization algorithms in MATLAB code are linked to Finite Element Method (FEM) solution technique (Ansoft HFSS-software) to simulate the antenna. The optimized compact antennas are fed by a microstrip line and built on an FR-4 substrate with 30 x 30 mm2 surface area and 1.5 mm thickness. The radiation characteristics of the designed antennas are completely analyzed, and the VSWR is then compared with the measurements to check the validity of the numerical results. Keywords: UWB Antenna, Central Force Optimization (CFO), Gravitational Search Algorithm (GSA).
