From Antenna to Filter or from Filter to Antenna
2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018This paper presents the two filtering antennas. One (type-A) is to design an antenna, which simultaneously realizes the filtering performance. The other one (type-B) is from a filter to design an antenna. The type-A filtering antenna obtained a high selectivity by etching slots on a single patch. The radiation nulls can be controlled individually.

Banwidth Reconfigurable Filtering Antenna
Wireless Personal Communications, 2019A microstrip bandwidth reconfigurable filtering antenna is implemented by simply tuning the transmission zeroes. The proposed filtering antenna is developed by integrating the filter characteristics into the 50 Ω microstrip feed line of the antenna through two independent coupled resonators.

Bandpass Filter Inspired Filtering Patch Antenna
2021 IEEE MTT-S International Wireless Symposium (IWS), 2021A 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

Applied Mechanics and Materials, 2015
A review on the recent advancements made on filtennas are presented in this paper. RF fronts ends continue to generate a lot of research attention in communication systems due to the effect it has on the overall bit error rate and SNR. Issues such as compactness, interference and noise are addressed by embedding the bandpass filter into the antenna to ...

Filtering Antennas and Filter-Valve Circuits
Proceedings of the IRE, 1929Some methods of coupling together many circuits or antennas giving them simultaneous excitation from the same source of energy are described. The purpose of such arrangements is the construction of practical filter circuits (filtering antennas) giving square-topped resonance curves with good efficiency.
