Terahertz antenna with tunable filtering

Applied Optics, 2023
A terahertz (THz) antenna with tunable filtering is designed and numerically studied. A slotted monopole radiator with defected ground structure is used for operating with wideband response with an impedance bandwidth in the range of 3.80–11.98 THz for S 11 ≤ − 10 d B .

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

From Antenna to Filter or from Filter to Antenna

2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018
This 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.
