Design of the Compact Ultra-Wideband (UWB) Antenna Bandwidth Optimization Using Particle Swarm Optimization Algorithm

In this paper a particle swarm optimization (PSO) algorithm is presented to design a compact stepped triangle shape antenna in order to obtain the proper UWB bandwidth as defined by FCC. By changing the various cavity dimensions of the antenna, data to develop PSO program in MATLAB is achieved. The results obtained from the PSO algorithm are applied to the antenna design to fine-tune the bandwi...

Antenna Array Design using Dual Nested Complex Approximation

This paper presents a new practical approach to complex Chebyshev approximation by semi-infinite linear programming. The approximation problem may be general with arbitrary complex basis functions. By the new front-end technique, the associated semiinfinite linear programming problem is solved exploiting the finiteness of the related Lagrange multipliers by adapting finite–dimensional linear pr...

An Aperture-coupled Patch Antenna Design for Improved Impedance Bandwidth

The Method of Moments, implemented in 2.5-D with the multilayer Green’s Function, or implemented as a fully 3-D solution of Maxwell’s equations, is a popular method for microwave antenna simulations. Commercial software was used to simulate two different designs for a single aperture-coupled patch antenna element. The simulation results are compared with experimental data measured for antenna p...
