CPW Filters with Defected Ground Structures for RF and Microwave Applications
نویسندگان
چکیده
New coplanar waveguide (CPW) filters with a forkshaped defected ground structure (DGS) are proposed for radio-frequency (RF) and microwave applications. The miniature CPW DGS filters developed are based on the silicon technology. The filters are able to provide the bandstop characteristics with high attenuation in the stop band and low insertion loss in the pass band. A typical filter designed for Ka-band satellite communication systems exhibits an attenuation of 26.3 dB at a resonant frequency of 28.35 GHz.

Microwave Bandpass Filters Using Couplings With Defected Ground Structures
In this paper some novel types of microwave bandpass filters using defected ground structures are investigated. In the microstrip technology the use of defected ground structures (DGS) allows designs of filters with tight couplings, without the necessity of using very narrow coupling gaps. In multilayer filters DGS can be used as coupling elements between resonators, allowing very compact filte...
