      Accés restringit per política de l'editorial
      In this paper, an uniplanar RF-MEMS second-order bandpass filter with reconfigurable centre frequency is presented. It is based on half-wavelength slotline resonators, which are loaded using RF-MEMS switches connected ...

    • RF-MEMS uniplanar 180º Phase Switch based on switching between two out-of-phase paths 

      Llamas Morote, Marco Antonio; Pradell i Cara, Lluís; Girbau Sala, David; Ribó, Miquel; Lázaro Villa, José Antonio; Giacomozzi, Flavio; Margesin, Benno (2011)

      Accés restringit per política de l'editorial
      A phase switch based on switching between two twoport passive networks with a phase difference of 180º is reported. Two RF MEMS single-pole-double-throw structures are used to select the phase path. The fabrication is ...

    • Small handset antenna for FM reception 

      Aguilar, David; Anguera, Jaume; Puente Baliarda, Carles; Ribó, Miquel (2008-10)
      Article
      Accés restringit per política de l'editorial
      A passive internal handset antenna for FM reception is presented using electromagnetic simulations as well as laboratory experiments. Received signal for the antennas have been demodulated and the quality of the audio ...

    • Uniplanar bandpass filters based on multimodal immitance inverters and end-coupled slotline resonators 

      Contreras Lizarraga, Adrián Arturo; Ribó, Miquel; Pradell i Cara, Lluís; Blondy, Pierre (IEEE Microwave Theory and Techniques Society, 2013)
      Article
      Accés restringit per política de l'editorial
      This paper presents the design and implementation of uniplanar bandpass filters that use end-coupled slotline resonators and a new kind of multimodal immitance inverter. These inverters are based on an asymmetric ...
