Parametric studies of ring and parallel coupled line resonators for matched bandstop filter design [PDF]
, 2019 Recently, matched bandstop filters had become a substantial part of modern RF and microwave systems. However, in these types of filters, the key problem in the couplings of any microstrip resonators to transmission microstrip line is the variation or ...

X-Band Waveguide Reflectionless Filtering Antenna Array With High Selectivity
IEEE Open Journal of Antennas and PropagationIn this paper, a waveguide reflectionless filtering antenna array with high selectivity is proposed. Instead of reflecting the out-of-band signal back to the source, the proposed antenna array dissipates the energy through a lossy network, which can ...
