The Resonance Principle and Designing Method of Multi-Bands Microstrip Antenna with Branch Shape
Abstract: In this paper, a kind of three-bands microstrip antenna composed of three branches was designed. Also, the S11 parameters of the antenna were simulated and measured. After that, the relationship between the dimension of antenna and the resonance frequency of antenna was analyzed by scanning the dimension parameters. At the same time, the results of dimension scanning were explained by analyzing the distribution of surface currents on the antenna. In order to gain larger attenuation in stopband than the antenna with three branches, an antenna composed of four branches was designed and its S11 parameters were simulated and measured. Then, an antenna occupying smaller dimension than the above antennas was proposed and the principle of widening its frequency bandwidth was stated. In the end, the general method of designing this kind of antenna was concluded.
