High-power Millimeter Wave The Flaps Antenna Theory And Experimental Research

With the development of high-power microwave technology to millimeter-wave band , The HPM transmitting system has higher requirements for processing technology of the traditional Parabolic transmitting antenna.it is three-dimensional structure characteristic of parabolic antennat that makes processing difficult in the millimeter-wave band and costs much.To slove this problem,the foreign Scholars have proposed a new kind of reflectors antenna which replace the traditional reflector. At present, the Flaps antenna only is used in low medium power microwave domain ,But it has not found in the high power launching system.In this paper, the review about the development of reflectarray is presented in recent years, including three representative reflectarray structures. the size element structure has been choosen and the reflector antenna of 400 milimeter aperture is designed,processed in ka-band and Experimental Research has been done.and the Flaps antenna performance analysis program is compiled, flaw of the computer hardware has been solved when the simulation software simulation heavy- aperture Flaps antenna. Based on these researchs, the reflector antenna of 1200 milimeter aperture is designed in ka-band, The curve between Processing accuracy and gain is given.my main work includes the following aspects:1.According to the element patch boundary conditions, chooseing specific element model, the phase curve between unit size and scattered field is obtained by HFSS.2.Through computating microstrip line power capacity, the antenna power capacity is obtained.3.By geometrical optics, compiling analysis program,Phase-shift of every element is obtained.4.Using aperture field integration method, compiling the Flaps antenna performance analysis program, compared calculating results with the simulation results to verify the correctness of the theory and program.5.Based on these researchs, the Flaps antenna was designed and carried out experimental study, and then improve theory and the analysis program.
