Abstract
With the development of communication technology, microwave technology is more and more used in communication, radar, environment detective and medicine field, microwave and RF are widely used. Especially in commercial field such as cell phone, personal communication system, WLAN,the car carries a millimeter of wave to defend to bump radar, living broadcasting satellite for broadcasting and television, GPS, RF identification tagging, UFB wireless communication and radar system, and, the remote sensor system for microwave environment. At the same time, microwave technology is in great need by the defense system for Have no source and Have a source orientation, communication and weapon control system. Microwaves system possesses lots of advantages such as BFB and The view spread, these are the vital factors for terrestrial and satellite communication, and this also accelerate the development of microwave component.
With the frequent resources becoming more and more limited, the design technology of filters with high frequent selecting characteristics becomes a important study field.On the basis of the studies of Miscellaneous wave restrain technology of tiny take structure band-pass filter,
