摘要：

By adding two different shape parasitic coupling elements at the radiating edge of a feeding transfer metal patch, a single feed point, good conformal shape, compact multiband microstrip antenna was developed. The proposed microstrip antenna is consisting of a ground plane, a feeding transfer metal patch, a meander-line patch parasitic coupling element and a T-shaped patch parasitic coupling element. The resonant frequency and bandwidth of the antenna are determined by the structure of the meander-line patch parasitic coupling element,the T-shaped patch parasitic coupling element, and the mutual coupling between the two parasitic elements and the feeding transfer element. The proposed antenna achieves multiband resonant frequencies that can be tuned independently by adjusting individual structure parameters. The associations between the antenna resonant frequencies and the structure parameters are simulated by electromagnetic simulation software, and it is shown that the antenna can typically work in 0.972~0.988 GHz,2.178~2.27 GHz and 3.293~3.356 GHz. The measurement results fit very well with the simulation, which validates the multiband microstrip antenna design method using parasitic elements excited by single feed point. © 2018, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
