Ferrando-Rocher, Miguel, Herranz-Herruzo, Jose Ignacio, Valero-Nogueira, Alejandro, Bernardo-Clemente, Bernardo Antena plana con polarización circular para comunicaciones por satélite en banda Ka: desafíos y resultados URI: http://hdl.handle.net/10045/114124 DOI: ISSN: Abstract: This paper reports the design and measurements of two radiating panels (TX / RX) for satellite communications on the move in Ka-band. A multilayer structure, both in the power distribution network and in the circularly-polarized radiating element, is adopted to ensure the demanded bandwidth. These panels provide answers and solve problems for future antennas with similar characteristics.
