open stubs filtersslotted ground planeThis work reports on a modified version of λ/2 open stubs bandpass filters (λ/2-OSBPFs) and λ/4 open stubs bandstop filters (λ/4-OSBSFs) for wide/narrow bandwidth operation. When wide bandwidths (for λ/2-OSBPF) or narrow bandwidths (for λ/...
Moreover,a compact microwave combiner is designed with the EBG structure,which contains two bandstop filters and one "T" junction. 应用该电磁带隙结构设计了一个微波合路器,包括两个EBG结构带阻滤波器和一个T型分支线,可以将两路频率不同的微波信号进行功率合成。 更多例句>> 5...
A dielectric rod resonator with the dominant TM/sub 01/spl delta// mode proposed realizes a strong coupling between the resonator and a waveguide. The design is performed to obtain the best separation from the other higher modes. Bandpass and bandstop filters with excellent spurious characteristics...
This work reports on a modified version of λ/2 open stubs bandpass filters (λ/2-OSBPFs) and λ/4 open stubs bandstop filters (λ/4-OSBSFs) for wide/narrow bandwidth operation. When wide bandwidths (for λ/2-OSBPF) or narrow bandwidths (for λ/4-OSBSF) are required, conventional ...
This paper develops a novel ultra-wideband bandpass filter by cascading a broadband bandpass filter with another broadband bandstop filter. Properly selected impedances of transmission lines achieve broadband bandpass and bandstop filters and make independent designs possible. Detailed design and synthesis pr...
A tunable, substrate integrated, high Q bandpass-bandstop filter cascade is demonstrated that is capable of providing up to 100 dB of isolation between two dynamically selectable frequencies of interest. Evanescent-mode cavity filters are used in the cascade to allow high quality factors and wide tu...
They are used as special low-pass, high-pass, bandstop, and bandpass filters6. The most common configurations comprise arrays of dipoles or their complementary structure (slots) arranged in a 2D planar surface. At their resonant frequency, the dipole array is characterized by totally reflecting ...
In this paper, a new switchable absorptive bandstop to bandpass filter using dual mode ring resonator is presented. This switchable filter provides two modes of operation which is absorptive bandstop and bandpass response. The first part of this paper presents a theoretical analysis of the absorptive...
A good agreement between simulation results and measurements has been achieved. Experimental results show that this type of filter can be switched either to perform the matched bandstop or bandpass response. 展开 关键词: Band-pass filters Resonator filters Matched filters Filtering theory Switches ...
