A New Family of Multiband Waveguide Filters Based on a Folded Topology

Melgarejo, Juan Carlos; Cogollos, Santiago; Guglielmi, Marco; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers, 2020-07)

[EN] In this article, we describe a new family of multiband waveguide filters based on a folded topology. The folded topology allows to use the filters of different orders and the introduction of transmission zeros. The ...
A Systematic Design Procedure of Classical Dual-Mode Circular Waveguide Filters Using an Equivalent Distributed Model

Cogollos Borras, Santiago; Brumos Vicente, María; Boria Esbert, Vicente Enrique; Vicente Quiles, Carlos Pascual; Gil Raga, Jordi; Gimeno Martinez, Benito; Guglielmi, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2012-04)

In this paper, we propose a systematic procedure for the accurate design of classical dual-mode filters in circular waveguide technology. The design procedure is based on the previous synthesis of an intermediate distributed ...
An Efficient Technique to Assess the Convergence of the Multimode Equivalent Network for Waveguide Devices

Gomez Molina, Celia; Quesada Pereira, Fernando; Alvarez Melcon, Alejandro; Boria Esbert, Vicente Enrique; Guglielmi, Marco (Institute of Electrical and Electronics Engineers, 2018-02)

[EN] Numerical methods are widely used to analyze and design microwave components for communication applications.In the implementation of any numerical technique, however, there are always a set of parameters ...
Design of Hybrid Folded Rectangular Waveguide Filters With Transmission Zeros Below the Passband

Carceller Candau, Carlos; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique; Guglielmi, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2016-02)

The design and physical implementation of hybrid folded rectangular waveguide filters providing multiple transmission zeros (TZs) below the passband are considered in this paper. These structures offer great flexibility ...
Efficient Design of Waveguide Manifold Multiplexers Based on Low-Order EM Distributed Models

Cogollos Borras, Santiago; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique; GUGLIELMI, MARCO; Brumos Vicente, María; Gimeno Martinez, Benito; Raboso García-Baquero, David (Institute of Electrical and Electronics Engineers (IEEE), 2015-08)

In this paper, a new systematic technique to design manifold-coupled multiplexers in waveguide technology is proposed. The new technique uses generalized low-order electromagnetic (EM) distributed models, which constitute ...
Filtros en guía de alto aislamiento acoplados por híbridos y aplicaciones en duplexores.

Coves Puelma, Paola (Universitat Politècnica de València, 2022-12-28)

[ES] El uso de circuladores en multiplexores de entrada en satélites genera varios inconvenientes. Entre ellos, la falta de reciprocidad de la estructura, el uso de ferritas para construir los circuladores, el alto grado ...
Full-wave analysis of dielectric-loaded cylindrical waveguides and cavities using a new four-port ring network

Penaranda-Foix, Felipe L.; Janezic, Michael D.; Catalá Civera, José Manuel; Canós Marín, Antoni Josep (Institute of Electrical and Electronics Engineers (IEEE), 2012-09)

In this paper, a full-wave method for the electromagnetic analysis of dielectric-loaded cylindrical and coaxial waveguides and cavities is developed. For this purpose, a new four-port ring network is proposed, and the ...
