A decoupling structure for array antenna

A decoupling structure of MIMO antenna system is designed. The crossed dipole structure is used in the antenna, which has better radiation characteristics while reducing the array aperture through miniaturization and artificial dielectric layer (ADL) decoupling structure. The simulation software Ansoft HFSS is used to optimize the array. The results show that the array has good isolation in the working frequency band, and the gain of the two - in - one unit is 8.5dbi.
