New multimode irregular microstrip resonators and designs of wideband bandpass filters based on them are being theoretically and experimentally investigated. A central multimode resonator electromagnetically connected with single-mode or two-mode resonators at the input and output of a structure are used in the developed filters. It is the first experience giving the possibility of combining inherent...
The diplexers based on 2D electromagnetic crystal are investigated with the help of the numerical electrodynamic analysis of 3D models. The input half-wave resonator has rolled up strip conductor in the claimed microstrip designs tuned with nearly adjacent bandwidths. It allows to coordinate channels rather easily. Such resonator in the first two-channel device at the same time interacts with pair...
The natural frequencies of the multimode microstrip resonator «hairpin with stub» were investigated from its constructive data. Application in the resonator of the stub allows not only to observe on amplitude-frequency characteristic the poles of power attenuation, and also to considerably reduce frequencies of all its even modes of oscillations. At the same time frequencies of odd modes don't change...
The microstrip broadband band-pass filters based on the irregular meander are investigated. It is shown that the connection with a screen of conductors of utmost quarter wave resonators results in significant improvement of frequency selective properties the filters.
Microstrip broadband filters based on the multimode resonator, having conductors in the shape of an irregular meander are investigated. The increase of the periods of the meander electromagnetically connected with several single-mode resonators allow considerably to improve frequency selective properties of filters.
The properties of microstrip structure with the regular resonators and based on 2-D photonic crystal with dimension 2??3 are investigated theoretically and experimentally. An opportunity to create filters with high frequency selective characteristics and based on 2-D microwave design is demonstrated.
Microstrip band-pass filters based on the multimode resonator, having conductors in the shape of a rectangular ring are investigated. Such devices because of the high steepness of slopes of a passband and an extended high-frequency stopband can have high frequency selective properties.
