A compact customizable tunable EBG filter

Micromachined tunable filter using fractal electromagnetic bandgap (EBG) structures

A tunable bandstop filter using fractal electromagnetic bandgap (EBG) structure is designed, simulated and fabricated. The uniform fractal EBG U-FEBG) structure is realized by replacing the etched rectangular holes with a Minkowski loop generator. A new technique of doubly tapered ractal EBG (DT-FEBG) structure is designed by non-uniform Kaiser distribution on the fractal structures. The Kaiser...

Compact tunable filter based on microfiber Bragg grating

Tunable filters for wavelength-division multiplexing transmission system are essential. Fiber Bragg grating (FBG) is one of the best candidates for this application. The wavelength shift of FBGs can be tuned by applying different temperature, hydrostatically pressure and strains (in traction or/and compression). A comprehensive study of using these three parameters as being tunable filters was ...

Design of Compact Tunable Bandpass Filter for Wideband Application

A design of compact ultra wideband (UWB) microstrip bandpass filter (BPF) with tunable notch response of wireless communication system is presented in this paper. The five order bandpass filter was designed using optimum distributed highpass integrated with Defected Microstrip Structure (DMS). The bandpass filter was designed at wideband frequency from 2.96 GHz to 10.1 GHz. The insertion loss a...

Novel Coplanar EBG Low Pass Filter

The traditional coplanar electromagnetic bandgap (EBG) structure is analyzed. The method is studied to lower the center frequency and broaden the bandwidth in this paper. A novel structure of U-bridged EBG power plane is proposed. The simulation and test results show that the bandwidth of the new structure is 4.32GHz, and the lower side cutoff frequency is at 380 MHz with the stopband depth at ...
