A Varactor-Based Reconfigurable Filtenna

IEEE Antennas and Wireless Propagation Letters, 2012
This letter details a new reconfiguration technique for implementing frequency-tunable bandpass filters. This is achieved by changing the filter total capacitance via an integrated varactor within its structure. The reconfigurable bandpass filter is then incorporated within the feeding line of a printed antenna to form one structure.

Electronically reconfigurable filtenna for cognitive radios

Microwave and Optical Technology Letters, 2016
ABSTRACTA frequency tunable and bandwidth reconfigurable antenna with ring slot resonators embedded into its ground plane is presented. To achieve the bandwidth reconfigurability, two PIN diodes are inserted to couple or decouple two pairs of ring slot resonators from the antenna feed line.

A Compact Filtenna for C-band applications

2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI), 2022
This paper presents a low profile filtenna designed for C-band applications. The proposed device exploits a rectangular patch antenna with parasites and directly connected to a compact filter, realized etching out properly designed spirals from the patch feeding line.

Compact Wideband Gain-Agile Receiving Filtenna

2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2019
A compact wideband gain-agile receiving filtenna is presented. The receiving filtenna is a co-design, which is organically combined by a compact passive filtenna and a variable gain amplifier (VGA) circuit. In the design, the active feeding network consists of one VGA circuit and two feeding strips connected by a metal post. Its gain-agile is empowered

OLR-filtenna for Wi-Fi applications

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Microstrip open loop resonators with annular or square configuration are widely used in the design of filters and antennas. In this paper a new compact microstrip OLR based filters are designed and analyzed. This filter configuration is extended to work as a filter antenna.

A new compact stripline patch filtenna module

Journal of Electromagnetic Waves and Applications, 2016
AbstractIn this paper, a new compact stripline patch filtenna module (SLPFM) has been proposed, designed, and fully investigated using the well-known electromagnetic simulator (CST_MW simulator). The objective is to design and fabricate a movable and compact microstrip patch chip (MS-Chip) mounted on a microstrip motherboard (MS-motherboard).

Overlay cognitive radio using MIMO reconfigurable filtenna

2016 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2016
Overlay cognitive radio is described in this paper. Channel activity is endlessly guide by the Wide band sensing antenna and a reconfigurable filtenna need to change the performing frequency. MIMO antenna system is considered to reduce multipath fading and to improve channel capacity.

Design of Compact Filtennas with Enhanced Bandwidth

2018 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2018
Two compact, wideband filtennas are simulated and then measured. For the purpose of extending impedance bandwidth, the designs are introduced by organically uniting a monopole with a band-pass filter, and then regulating their mutual coupling. This method is adopted by incorporating filtering elements into antennas with near-field resonant parasitic ...

Design of Edge-Coupled Microstrip Patches Filtenna

Proceedings of the 6th International Conference on Engineering & MIS 2020, 2020
A microwave structure that combines filtering and radiating functions is presented. The structure consists of three patches, two of which are aperture-fed, printed on stacked substrates. The array can be considered as three-pole edge-coupled filter with radiating resonators.
