Abstract

The invention discloses a dual polarization array antenna with high polarized isolation; the dual polarization array antenna comprises two radiation pasters, a [pi] type mutual coupling suppression structure arranged between the two radiation pasters, a parasitic coupled floor and a grounding capacitive loading ring; the grounding capacitive loading ring is vertically arranged on the parasitic coupled floor; the [pi] type mutual coupling suppression structure and the grounding capacitive loading ring are mutually vertical to each other. The antenna adds the [pi] type mutual coupling suppression structure between the array elements, thus effectively improving the antenna polarized isolation, and keeping other performance of the antenna to be well.

Description

technical field [0001] The invention relates to an antenna structure, in particular to a dual-polarized array antenna with high polarization isolation that can be applied to a 5G communication system. Background technique [0002] Multiple-input multiple-output technology can increase the data capacity by increasing the number of channels and improve the adaptability of the system. Compared with the traditional method of increasing the frequency band and power, it has huge advantages and will become an important component of the upcoming 5G communication technology. part. At present, with the further development of MIMO technology, higher and higher requirements are put forward for the mutual coupling suppression of components. [0003] There are already many methods to effectively improve mutual coupling suppression (polarization isolation), but most of the methods can only be applied to single-polarized array antennas; for mutual coupling suppression networks, the working...
