Abdo-Sánchez, María Elena
; Martín-Guerrero, Teresa María; Page de la Vega, Juan Enrique; Esteban Marzo, Jaime; Camacho-Peñalosa, Carlos (2013-09-13)
Recently, the authors introduced a novel planar radiating element that exploits the characteristics of the slotline microstrip coupling to obtain a microstrip-fed slot with broadband matching. This paper reviews the main ... -
Circuito equivalente del strip-slot complementario como red asimétrica con pérdidas
Esteban Marzo, Jaime; Abdo-Sánchez, María Elena; Martín-Guerrero, Teresa María; Camacho-Peñalosa, Carlos (2017-09-26)
The complementary strip-slot can be successfully modeled by means of a lattice equivalent circuit, with realizable immittances. In the case of the misaligned complementary stripslot, useful in series fed arrays, the lattice ... -
Disipación de potencia en redes en celosía: la radiación del strip-slot complementario
Abdo-Sánchez, María Elena; Martín-Guerrero, Teresa María; Esteban Marzo, Jaime; Camacho-Peñalosa, Carlos (2015-09-21)
A circuit property of symmetrical lattice networks is derived and applied to the analysis of symmetrical twoport electromagnetic structures. This property is related to the independence of the power dissipation in the ... -
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 ... -
Equivalent Circuit Modelling of Non-Symmetric Reciprocal Lossy Electromagnetic Structures
Abdo-Sánchez, María Elena; Martín-Guerrero, Teresa María; Esteban Marzo, Jaime; Camacho-Peñalosa, Carlos (2018-06-04)
Lattice-network-based equivalent circuits of lossy symmetric reciprocal electromagnetic structures have shown superior performance when compared to other topologies like the T- or PI- networks. This is due to the realizability ... -
Measuring odd- and even-mode propagation constants of coupled-lines by means of the lattice network
Hernández-Escobar, Alberto; Abdo-Sánchez, María Elena; Esteban Marzo, Jaime; Martín-Guerrero, Teresa María; Camacho-Peñalosa, Carlos (2019-10-30)
A classic method for measuring the propagation constant of transmission lines is the one proposed by Bianco and Parodi more than four decades ago [1]. It is based on the invariance of the cross ratio of four complex numbers ... -
Modelling asymmetric two-port reciprocal microwave structures by means of compact equivalent circuits
Abdo-Sánchez, María Elena; Martín-Guerrero, Teresa María; Esteban Marzo, Jaime; Camacho-Peñalosa, Carlos (2019)
Effective microwave systems design requires powerful and reliable modeling techniques. Today modern CAD tools provide such support from device physics to circuit level or from electromagnetics to system level. Nevertheless, ... -
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 ... -
