(2014-01-01)
Article
Accés restringit per política de l'editorialThe design, fabrication, and characterization of a frequency-reconfigurable antenna for the United States Public Safety (PS) wireless communication applications are presented. This antenna is quad-band operating in the PS ... -
Dual-band Sierpinski fractal monopole antenna
(Institute of Electrical and Electronics Engineers (IEEE), 2000)
Text en actes de congrés
Accés obertA new top-loaded reduced-sized dual-band (1.9 GHz and 3.5 GHz) monopole antenna for wireless communications is presented. The antenna provides better than -15 dB input return loss and keeps the same radiation pattern over ... -
