To improve the rejection roll-off of the lower stopband, a pair of folded slots are etched at both ends of the ridge to form a quarter-wavelength (λ/4) resonance for introducing a TZ below the ...

Abstract: This article proposes a novel design approach for miniaturized, highly selective, self-packaged, and wide-stopband filtering slot antennas based on C- and T-type folded substrate integrated ...
