Seven bands Loop antenna optimized by using particle swarm optimization algorithm

A novel design of Seven band loop antenna for the frequency range from 0.7Ghz to 6Ghz covering all Wireless systems, is described and simulated. the antenna is planar inverted F, optimized using Particle swarm optimization with non-uniforms chromosome matrix to locate the slots on the resonator part of the PIFA. The proposed antenna is created and simulated by CST microwave studio and verified by Ansoft software HFSS.the simulation result shows that both software are in good agreement and the antenna provide a minimal gain of 3dBi and a maximal gain of 7dBi.
