Blind spot mitigation in phased array antenna using metamaterials
In this work, a metaradome based on a fakir’s bed of nails is designed and tested in order to suppress the blind directions of a 100-element antenna array. The antenna is a microstrip array designed to operate in X-band. ... -
Compact ultra wide band microstrip bandpass filter based on multiple-mode resonator and modified complementary split ring resonator
A new class of broadband microstrip filters for Ultra Wide Band (UWB) applications is proposed. In the design, different stages of parallel-coupled microstrip line and other stages with a Modified Complementary Split Ring ... -
Desarrollo de software de simulación basado en el método numérico FDTD y su aplicación en el diseño de dispositivos de microondas miniaturizados
Esta tesis es fruto de mi participación en diferentes proyectos en algunos casos como gestor, en otras ocasiones como investigador, aunque yo diría más bien como desarrollador. La tesis la he estructurado en 4 capítulos: 1) ... -
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation ... -
Implementacion de línea de ε negativa en tecnología stripline
In this work, a negative-ε equivalent response medium is proponed in stripline technology. To achieve band rejection behaviour, Complementary Split Ring Resonators (CSRR) are placed in the central conductor strip of ... -
Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria
In this work a dual band GSM/UMTS antenna is proposed. The antenna is based on a stacked planar structure, where the combination of collimation by Enhanced Transmission and the use of parasitic director elements is ...
