Abstract

An inset feed Microstrip radiator has been designed and developed for operation at 2.4GHz frequency. The Microstrip patch antenna (MPA) parameters were designed using IE3D®TM EM simulator (version 14.0) and optimized with an evolutionary stochastic optimizer i.e. Particle Swarm Optimization (PSO) technique. Optimized results show that the antenna has a bandwidth of 33.54 MHz (<-10dB) in the range 2.38355 GHz to 2.41709 GHz and a maximum return loss of -43.87dB at the resonant frequency of 2.4 GHz. The patch antenna is fabricated and the important parameters like return loss, VSWR etc were measured. The measured parameters match with the simulated results well within the tolerable limits.
