Abstract

In this design, a microstrip patch antenna was designed and simulated using the CST software. Despite the fact that proposed antenna has only one feeding line and one dielectric substrate, multiband operation frequency is obtained. The proposed antenna is loaded by two narrow slots closed to the radiating edges, and two chip capacitors on the middle of the slots. The values of the resonance frequencies of the proposed antenna depend on the value of the capacitors. By changing the capacitors values, the ratio of the resonance frequencies are decreased due to the increase of the capacitors value, which changes the distribution current on the surface of the patch.
