SIW Resonator-Based Duplex Filtenna

IEEE Antennas and Wireless Propagation Letters, 2021
In this communication, a low-profile single-layered duplex-filtenna scheme is proposed by using two feeds and a common substrate integrated waveguide (SIW) cavity. A rectangular slot is carved on the top of the cavity along the narrower side of the SIW, which splits the cavity into two unequal parts.

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 ...

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.

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.

Frequency reconfigurable dual-band filtenna

AEU - International Journal of Electronics and Communications, 2020
Abstract In this paper, a compact size frequency reconfigurable dual-band filtenna (Filter +Antenna) is proposed for WLAN, WiMaX and C-band applications. The filtenna is designed by a switchable SRR (i.e. Two switches are used in inner and outer split rings) band pass filter (BPF) and a CSRR based antenna.

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 microstrip ultra-wideband filtenna

2014 15th International Conference on Electronic Packaging Technology, 2014
In this paper, a compact ultra-wideband antenna with filtering functions is presented. It has a compact size of 32mm∗26mm∗0.8mm. The filtenna is fabricated on a common and low-cost FR4 substrate, with a relative dielectric constant of 4.4, and a loss tangent of 0.02.

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.

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.
