Design of dual-linearly-polarized microstrip array with composite right/left-handed transmission line as feed line

Abstract

A novel dual-linearly-polarized microstrip antenna array with series fed configuration is presented. Dual-linear-polarization is excited by upper side-feeding and lower aperture-coupled feeding. Meanwhile, the series-feeding configuration is realized by a composite right/left-handed transmission line. Compared with the traditional design, this array is of simple structure, small area
