偏振天线设计DESIGN OF VERY WIDE-BAND LINEAR-POLARIZED ANTENNAS * Eva Antonino, Marta Cabedo, Miguel Ferrando, Alejandro Valero Departamento de Comunicaciones, Universidad Politécnica de Valencia, Spain Abstract: In this paper, various designs for wide-band linear-polarized antennas based on the use of characteristic modes are presented. These antennas make use of a multiple feeding configuration to excite only those current modes presenting a behavior in accordance with the desired antenna specifications. Antennas for single and dual polarization are proposed and excellent results are obtained. 1. Introduction The increasing demand for wireless communication services spurs the need for antennas capable of operating at a broad frequency range, since it would be very attractive to cover all the emergen……
