Fabry-perot Resonator Printed Antennas

The Fabry-Perot resonator used in the optical domain has frequency selection function on the propagation of electromagnetic waves, adopt this structure to the antenna system can significantly increase the gain of the antenna. This thesis aims to use tapered-sized quasi-period square patchs FSS cover to apply in the research of realization of one of the broadband and high-gain printing antenna who asks for the help of Fabry-Perot resonator principle, expecting the low side lobe level and low back side lobe.Under a lot of physically applied situations request antenna not only has to have high gain, also need its side lobe level is low and backside radiation is low. too. Based on the Fabry-Perot resonator antenna radiation properties of printed.designed an antenna who worked in resonant frequency of 12.5GHz.adopted Quasi-periodic tapered-sized Frequency Selective Surface (FSS) as cover. U-slot patch antenna as radiator, constituted of the Fabry-Perot resonator high-gain printing antenna.Achieved a high gain antenna.who had low sidelobe level, low backside radiation, wide bandwidth and low-profile.The article analyzed the work mechanism of F-P resonator printing antenna, and the methods of lower the antenna side lobe. The whole wave analytical result is to ask for the help of CST microwave studio, and a kind of F-P resonator printing antenna is fabricated and mesured, the mesured data has proved the accuracy of the simulated results.
