Filtering Antenna Design and Implementation Techniques: Applications, Recent Developments, Challenges, and Future Opportunities

Journal of Engineering
Antennas and filters are two key components that make up the configuration of the radio frequency (RF) front end of any wireless communication system. While the antenna is responsible for transmitting and receiving signals in the system, the filter is ...

Continuously Frequency-Tunable Horn Filtennas Based on Dual-Post Resonators

International Journal of Antennas and Propagation, 2019
This work reports the concept and development of two mechanically frequency-tunable horn filtennas for microwave and millimeter-waves. Our design approach relies on the integration of a horn antenna with a mechanically tunable filter based on dual-post ...

Dual-band Metamaterial Filtenna for WiMAX Application

ELEKTRIKA- Journal of Electrical Engineering, 2019
Filter and antenna are the most important components in transmission and receiving signal in wireless communication system. The combination of a filter and antenna was known as filtenna. In this paper, a metamaterial band-stop filter is combine with a multiband antenna to produce a dual-band metamaterial filtenna.

Multimodal planar monopole filtenna for 5G applications [PDF]

AEU - International Journal of Electronics and Communications
[EN] This paper presents a novel planar filtering antenna (filtenna) with simple layout based on tightly -coupled different -length monopoles. Its design methodology is based on an even-mode/odd-mode decomposition of the monopole currents, and the combination of both modes in a multimodal circuit model that facilitates the design and tuning of the ...

Compact Ka‐band conical beam filtenna

IET Microwaves, Antennas &Propagation, Volume 17, Issue 3, Page 208-215, February 2023., 2023
A compact conical beam antenna composed by a filtering power divider (FPD) and circular open waveguide is presented. In order to reduce insertion loss in Ka‐band, the five‐way radial power divider and the cascaded filters are constructed using metallic waveguides.
