Abstract

Abstract

Based on the principle of the complementary antenna, a kind of dual-polarized antenna element is studied, which combines the printed dipole antenna and circular microstrip patch. The printed dipole antenna is the electric current radiation source and the circular microstrip patch is the magnetic current radiation source. The two polarization ports are composed of the electronic and magnetic radiation resource, respectively, which radiate dual polarized electromagnetic fields. The electromagnetic simulation and optimization design of the dual-polarized antenna are carried out using the full wave electromagnetic simulation technique, and the simulation results show that the isolation of the designed antenna is above 22 dB and the cross polarization level is lower than -20 dB at the boresight direction within the operational frequency range. The measured results of the fabricated antenna indicate that the Voltage Standing Wave Ratio (VSWR), port isolation degree and the cross polarization level can satisfy technical requirements.
