Abstract

A low-profile dual-polarized crossed dipole antenna on artificial magnetic conductor (AMC) surface is presented in this paper. The antenna consists of two orthogonal dipoles, a periodic arrangement of artificial magnetic conductors and a ground floor. The antenna has a section height of only 13mm (0.13λ0, λ0 is the wavelength in free space at 3 GHz). With utilizing the 6×6 unit cell of square patch based AMC, the antenna can achieve a wide band. To verify this design, a prototype of this antenna is designed, fabricated and measured. Measured results exhibit that bandwidth from 2.9 GHz to 3.32 GHz (S11< -10dB) for one port and from 2.995 GHz to 3.47 GHz (S22< -10dB) for another port are obtained, respectively. Meanwhile, the isolation between two ports is less than -30 dB, and stable radiation patterns are realized in operating frequency band.
