Abstract
A quadri-polarized antenna oscillator, a quadri-polarized antenna, and a quadri-polarized multi-antenna array are provided. The quadri-polarized antenna oscillator comprises four polarized oscillators, wherein midpoints of the four polarized oscillators are coincident; a polarization direction of a first polarized oscillator is a horizontal direction; a polarization direction of a second polarized oscillator is perpendicular to the horizontal direction; a polarization direction of a third polarized oscillator has a 45° angle with the horizontal direction; and a polarization direction of a fourth polarized oscillator has a −45° angle with the horizontal direction. By integrating four polarized oscillators having different polarization directions into one antenna oscillator, the width of the MIMO multi-antenna is reduced, and the horizontal space between two columns of dual-polarized antennas is not required any more, thus the deployment of LTE and 4G networks are favorably implemented without extra space requirement to the top surface of a base station.
