A frequency reconfigurable cell for beam-scanning reflectarrays
Rodrigo López, Daniel; Jofre Roca, Lluís; Perruisseau Carrier, Julien (Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialReflectarray antennas are excellent candidates for beam-scanning applications thanks to their low loss, light and quasi-planar structure and ease of electronic control. However, reflectarray antennas suffer from narrower ... -
Antenna array configurations for massive MIMO outdoor base stations
Artiga Campos, Xavier; Perruisseau Carrier, Julien; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialMassive MIMO predicts unprecedented capacity and energy efficiency improvements in future networks, by the use of base stations with hundreds of antennas. However the crucial question of determining suitable, or even ... -
Diplexor reconfigurable para estándares de transmisión y recepción WiFi-UMTS
Brito Brito, Zabdiel; Llamas Garro, Ignacio; Navarro Muñoz, Guillem; Perruisseau Carrier, Julien; Pradell i Cara, Lluís (2010)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper a reconfigurable diplexer for WiFi and UMTS transmit and receive bands is presented. The diplexer has four possible frequency and bandwidth states, and consists of two reconfigurable filters connected by an ... -
Filtro paso-banda con control preciso de frecuencia central y ancho de banda usando interruptores RF MEMS
Brito Brito, Zabdiel; Llamas Garro, Ignacio; Perruisseau Carrier, Julien; Pradell i Cara, Lluís; Giacomozzi, Flavio; Colpo, Sabrina (2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper a reconfigurable bandpass filter is presented. The filter is able to switch between two different states with a center frequency tunable range of 24 % in C band. Center frequency and bandwidth are precisely ... -
