A Broadband Cavity-Backed Slot for Series-Fed Arrays
(UMA Editorial, 2022-01-26)A pesar de que el diseño de antenas en el contexto de los sistemas de comunicaciones es uno de los desafíos más clásicos en la ingeniería de telecomunicación, las antenas para nuevas aplicaciones y servicios de reciente ... -
Análisis Preliminar del Strip-slot Complementario en Tecnología Stripline
A stripline-fed slot antenna configuration is proposed using planar technology. Its main advantages are the broad impedance bandwidth available and the radiation in only one half-space, which are obtained with the use of ... -
A Broadband Bow-Tie Cavity-Backed Slot for Traveling-Wave Arrays in the Millimeter-Wave Band
The use of bow-tie geometries to enhance the characteristics of a radiating element previously proposed by the authors is presented. The previous element consisted of a broadband cavity-backed slot in transmission ... -
Building Arrays with the Unidirectional-Radiating Complementary Strip-Slot
Hernández Escobar, Alberto; Abdo-Sánchez, María Elena
; Camacho-Peñalosa, Carlos (Iñigo Cuíñas Gómez, 2021-09)
An upgraded version of the complementary stripslot radiating element is reviewed. The original radiating element consists in a microstrip-fed slot in transmission configuration. In the proposed modification, the slot is ... -
Eigenstate equivalent circuit for bi-periodic surfaces: Application to three parallel dipoles
Hernández Escobar, Alberto; Abdo-Sánchez, María Elena; Esteban Marzo, Jaime; Martín-Guerrero, Teresa María; Camacho-Peñalosa, Carlos (2022-03-29)
An equivalent circuit for the unit cell of bi-periodic surfaces is proposed. The equivalent circuit is general and simple. It is based on the decomposition of the eigenmodes of the structure and it takes into account the ... -
Elemento radiante de banda ancha en microstrip cerrada para arrays alimentados en serie
A previous radiating element in transmission configuration proposed by the authors is alternatively implemented using enclosed microstrip configuration. The new implementation overcomes fabrication issues and improves its ... -
Novel Implementation for a Cavity-Backed Slot Fed in Transmission Configuration
A novel radiating element proposed previously by the authors is alternatively implemented using enclosed microstrip configuration. The radiating element shows broad impedance bandwidth and unidirectional radiation pattern. ... -
On the eigenstate equivalent circuit for lossy asymmetric two-ports and its applications
Esteban Marzo, Jaime; Hernández Escobar, Alberto; Abdo-Sánchez, María Elena; Mateos-Ruiz, Pablo; Martín-Guerrero, Teresa María; Camacho-Peñalosa, Carlos[et al.] (2022)
An equivalent-circuit topology for two-port lossy non-symmetric reciprocal networks is presented [1]. The circuit topology is based on the eigenstate decomposition. The proposed circuit consists of two immittances and two ... -
Ranura de Banda Ancha en Doble T Sobre Cavidad para Arrays Alimentados en Serie
A previous radiating element for series-fed arrays proposed by the authors and based on a Cavity-Backed Slot (CBS) is modified to improve its bandwidth. In order to do that, the slot is modified to reduce its resonance ...
