Technical field
The present invention relates to the reconstruct paster UWB wave filter based on multimode resonance, there is multimode in UWB in this wave filter, bandpass is realized in UWB, can well selecting the signal in ultra broadband, ultra broadband (UWB) band filter has important practical value in wireless communication technology and radar system and ultra broadband location.
Background technology
Band filter can allow the signal in passband well pass through, and filters the signal beyond passband and well realizes the selectivity characteristic of band filter.But being as the development of modern communication technology, the bandwidth of required signal is more and more wider, now that the requirement of ultra broadband is more and more higher, so the reconstruct paster UWB wave filter based on multimode resonance just has significantly high practical value.
UWB or wide-band microwave wave filter are the ingredients that modern communication technology application is very basic, for instance UWB, radar system, alignment system, wireless communication technology, the fast development of this special dimension has promoted the development of various ultra-wide band filter.In February, 2002, FCC (FCC) ratifies 3.1-10.6GHz frequency range for business telecommunication, and therefore UWB is widely used.But, some technology require beyond 3.1-10.6GHz frequency range, the shortcoming that now compensate for narrow bandwidth in this respect based on the reconstruct paster UWB wave filter of multimode resonance, significantly broaden bandwidth, allow more signal can pass through wave filter, in addition there is multimode in passband in this ultra broadband (UWB) band filter, has higher practical value in wireless communication technology.Development along with integrated communication system, modern electronic product is more and more higher for microminiaturized requirement, the studied person's extensive use of undersized technology is subtracted so various, ultra broadband (UWB) band filter is achieved that structure macro, has reached to subtract undersized target referring now to former cascade structure.
Occur in that a lot of mentality of designing in recent years, such as multimode resonator (MMR), cascade structure etc., although but these structures can realize filter effect, but volume is big or selects poor performance or limited bandwidth.So design can select in UWB signal better based on the reconstruct paster UWB wave filter of multimode resonance and better select except the signal on UWB both sides simultaneously, better realizing the selectivity of ultra broadband, ultra broadband (UWB) band filter has great importance.
Summary of the invention
It is an object of the invention to provide the reconstruct paster UWB wave filter with multimode resonance, this wave filter can better select the signal in ultra broadband and occur multimode in passband, the little target reaching microminiaturization of this reconfigured geometry size, has significantly high using value to wireless communication technology, radar system, alignment system.
The technical solution adopted in the present invention:
Reconstruct paster UWB wave filter based on multimode resonance, including being formed at the symmetrical reconstruct paster (101) of dielectric-slab upper surface, port paster (103), it is characterized in that, the reconstruct paster of affiliated symmetry includes Low ESR paster (1011), Low ESR paster (1012), high impedance paster (1013).
