A Design of Low-profile Miniaturized Dual-polarization Antenna

Abstract

With rapid development of modern wireless communication systems, there is an urgent need for miniaturization and planarity antenna with lower profile, lighter weight and lower cost. Dual polarization shared dipole (DPSD)antenna can reduce almost half size of tradition dipole by multiplexing two polarized dipole arm structures. In this paper, based on artificial magnetic conductor (AMC) with reflective phase band-gap characteristics in a specific phase, a dual-polarized antenna with low profile, high isolation and high gain is designed. Simulation results show that the profile is down to 23mm, and improves the gain to 9.8 dB.
