Bandpass Filter Inspired Filtering Patch Antenna

2021 IEEE MTT-S International Wireless Symposium (IWS), 2021
A planar filtering patch antenna inspired by BPF (bandpass filter) prototype is proposed in this paper. The antenna has a very simple structure, while realizing multifunctional operation, including directional radiation and filtering functions. The principle of replacing the LC resonator of BPF prototype with a patch resonator is illustrated. The newly

Inductorless bandpass filters

IEEE Journal of Solid-State Circuits, 1970
The technique of designing inductorless filters by replacing the inductors in conventional LC filters with gyrators and capacitors is considered for the special case of the high-quality channel bandpass filters used in multiplex telephony. One particular gyrator circuit, which has been found to be very satisfactory, using two operational amplifiers and
