摘要: In this paper, a compact ultra-wideband (UWB) band-pass filter with sharp roll-off and improved out-of-band performance is designed manufactured. the proposed structure, modified one quarter-wavelength cross-shaped coupled lines (CCLs), also radial stub loaded resonator (RSLR), are implemented in order to reduce total size of UWB BPF. The RSLR able control two tuneable transmission zeros (TZs) separately CCLs can be properly so that unwanted pass band rejected. A prototype BPF fabricated tested. measured results good agreement simulated data structure shows selectivity filtering frequency interest.
