ABSTRACTMillimeter wave system has many distinct advantages such aS miniaturizing system components，increasing frequency band width，providing higher resolving power, uneasily influenced by atmosphere conditions，etc．This makes millimeter wave technique get the increasingly extensive application in radar,communications， electronic warfare，guidance，remote sensing，radiation survey,therefore the research ofmillimeter system is very vital for civil，the industry,national defense．The cooperating of PCSS and light pulse call produce hi曲power microwave，it is a new microwave source--hi曲power photoconductive microwave source．The keystone is the springing of charged PCSS by using small laser power can translatedirect current power to microwave power．It is the newest evolvement in high poweroptoelectronics by the combination of modern semiconductor technology and lasertechnology,it will be applied widely in the producing and controlling of microwave、the radiation and receiving ofmicrowave、the microwave communication and swash radar． In this dissertation，the system of high power photoconductive microwave SOBICeis studied in theory,simulation and experiment．The high power Photoconductive microwave source is mostly consisted of the design of PCSS、dielectric resonators、 output devices of the coupling of dielectric resonator and ultra broad band slot antenna, and realize the integration of all these devices mentioned above finally．The high power photoconductive microwave source investigated in thedissertation has good application foreground in both scientific research and engineering． The array of this microwave source can realize the synthesizing of space power、the array controlled by light of phase controlling，and enhance the exploration ability ofradars largely．The piece designed in this dissertation call achieve the pick-up of microwave signal whose central frequency is 3．5GHz and who has a certain bandwidth， further more，it haS some advantages such aS small volume、low facture cos
