Circular Microstrip Antenna

On the demand of miniaturization of antenna, this paper presents a circular microstrip antenna whose part of its port is sealed. Changing part of its magnetic wall into electric wall, then a decimals mode which exist between andis proposed. Elaborating the theory of reducing the resonant frequency with Bessel functions characteristics and resonance formula of circular microstrip antenna. Using the HFSS for simulation, the resonant frequency of the antenna change from 3.0 GHz to 1.2 GHz. The results prove the reliability of theory analysis. The size could be reduced nearly 60% compared with ordinary antenna. The antenna has a simple structure and can be applied to engineering application.
