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.

Banwidth Reconfigurable Filtering Antenna

Wireless Personal Communications, 2019
A 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.

A balanced filtering antenna

2015 IEEE 4th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2015
A balanced filtering antenna is proposed in this paper. It is composed of a wideband dipole antenna, a reflecting ground and a filter. The filter is utilized to replace the transmission line between two arms and the reflecting ground of the dipole antenna.

A Review on Filter-Antennas

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 ...

A Wideband Filtering Antenna Array With Harmonic Suppression

IEEE Transactions on Microwave Theory and Techniques, 2020
In this work, a wideband 2×2 filtering antenna array is proposed and studied for fixed beam applications. The device is composed of a patch antenna array and a slotline-based four-way filtering power divider served as the feeding network. The integration of the antenna and the feeding parts is not a simple combination but a co-synthesis, where the ...
