Title High gain antenna based on Fabry-Perot resonator
Abstract Fabry-Perot resonant antenna with planar space fed low profile structure, can significantly improve the antenna gain and aperture efficiency, is a new hot spot in the high efficiency, high gain antenna is studied. And with the utility model has the advantages of simple structure, small size, low cost, easy processing, in particular, can achieve the advantages of high directivity, etc., in the wireless communication is used more and more widely. F-P resonator was initially applied in the optical field. Due to the Fabry Perot structure on the propagation of electromagnetic wave with frequency selection, when the distance between the two panels, consistent with the resonant conditions, electromagnetic wave after penetrating F-P to in-phase superposition and enhanced, so as to improve the gain, beam width, play a role in similar focusing lens. When applied to the antenna, to increase the gain of the antenna and other parameters also play a very significant role. Study the theory of F-P resonator at the same time, this paper designs a use U-slot patch antenna as a feed antenna FSS structures as a cladding of Fabry Perot resonator broadband printed antenna. This paper analyzes the working principle of F-P resonator antenna, and various parameters on all aspects of the performance of the antenna effect, thus better on the antenna were optimized and improved. With the help of the HFSS software simulation analysis of the antenna model, so as to obtain a series of results.
