MULTI BAND DUAL POLARIZATION ANTENNA

摘要

The present invention relates to a multi-band dual polarization antenna. The multi-band dual polarization antenna includes: a dielectric substrate; a first dipole device and a third dipole device arranged vertically on one plane of the dielectric substrate; a second dipole device and a fourth dipole device arranged horizontally on the other plane of the dielectric substrate; and a feeding part having two or more feeding points which are connected to the first, second, third and fourth dipole devices and provide a current inputted from an external device to the first, second, third and fourth dipole devices. The first, second, third and fourth dipole devices have a plurality of radiation parts for radiation of a first frequency band and a second frequency band. According to the present invention, a compact dual polarization antenna can be realized by arranging a dipole antenna having a plurality of radiation parts on the dielectric substrate for realizing the dual polarization antenna operating in a high frequency band and a low frequency band at the same time.
