ANTENNA DECOUPLING APPARATUS, ANTENNA ARRAY, AND TERMINAL

摘要

The present invention provides an antenna decoupling apparatus, an antenna array, and a terminal. The antenna decoupling apparatus comprises: surface level ring-shaped interdigital structures and base level T-shaped structures; the structures at the two levels are connected by means of short circuit pillars; an electric current on the antenna array couples onto the ring-shaped interdigital structures, and, after going through the ring-shaped interdigital structures on each side, reaches the base level T-shaped structures via the short circuit pillars; when the electric current reaches a distance on the middle branches of the T-shaped structures that is half the wavelength, the electrical current at the end of said branches is zero, and the electric current coupled between the two antennas is neutralized.
