Microwave reflection tomographic array for damage detection of civil structures
Kim, Yoo Jin; Jofre Roca, Lluís; Flaviis, Franco de; Feng, Maria Q. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-11-30)
Article
Accés obertMicrowave tomographic imaging technology using a bifocusing operator has been developed in order to detect the internal voids/objects inside concrete structures. The imaging system consists of several cylindrical or ... -
Miniature multi-element antenna for wireless communications
Jofre Roca, Lluís; Cetiner, Bedri Artug; Flaviis, Franco de (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-05-31)
Article
Accés obertWe present a novel broad-band miniature antenna and employ it in a multi-element geometry with diversity capabilities for wireless communications. This antenna (diameter < 0.2 λ and thickness < 0.06 λ) consists of two ... -

Optimization of linear multielement antennas for selection combining by means of a Butler matrix in different MIMO environments
Grau Besolí, Alfred; Romeu Robert, Jordi; Blanch Boris, Sebastián; Jofre Roca, Lluís; Flaviis, Franco de (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-11-30)
Article
Accés obertAn optimized linear multielement antenna (MEA) is presented for selection combining schemes that improves the selection diversity gain and selection diversity capacity in medium and low multipath environments, with ... -
Small-size broadband multi-element antenna for RF/wireless systems
Cetiner, Bedri Artug; Jofre Roca, Lluís; Qian, J. Y.; Flaviis, Franco de (IEEE, 2003-10-31)
Article
Accés obertWe present a small-size broadband antenna specifically designed for integration with RF/wireless communication systems. The antenna is built on a printed circuit board and fed by a coplanar waveguide (CPW) to allow further ...
