Optimization of Resonance Frequency of Circular Patch Antenna at 5 Ghz Using Particle Swarm Optimization
The microstrip antenna is small in size, simpler and less expensive to manufacture. They are more compatible than reflector antennas with printed-circuit technology. The microstrip patch antenna is a type of antenna that is thin, and has easy manufacturability, which provides a great advantage over traditional antennas. The Particle Swarm Optimization (PSO) has been introduced to the electromagnetic community for few years. In this paper, PSO has been used for optimization of resonant frequency of circular probe-fed patch antenna. The investigation is made at a microwave frequency of 5 GHz.
