      Radio Frequency Interference (RFI) is probably one of the most important limiting factors in the accuracy of the brightness temperatures measured by microwave radiometers. Due to the proximity of the 'protected' L-band ...

    • Design and performance evaluation of a switched-beam antenna array for 60 GHz WPAN applications 

      Imbert Villà, Marc; Papió Toda, Anna; de Flaviis, Franco; Jofre Roca, Lluís; Romeu Robert, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2015)

      Accés restringit per política de l'editorial
      In this paper, the design and performance evaluation of a switched-beam antenna array to operate in the 60 GHz band for short-range WPAN applications is presented. In order to overcome the high path-loss attenuation at ...

    • Design and performance evaluation of millimeter-wave flat lens antennas for communications, radar and imaging applications 

      Imbert Villà, Marc (Universitat Politècnica de Catalunya, 2016-07-29)
