The present disclosure discloses an isolation structure of a large array antenna and an antenna. According to an embodiment of the present disclosure, a boundary plate is disposed between array elements of a large array antenna. The boundary plate has hollowed-out areas and is perpendicular to a plane where the array elements are located. The hollowed-out areas of the boundary plate form sub-areas with staggered patterns in the boundary plate to allow a coupling path of signals of array elements generated at the boundary plate and a radiation path of the array elements to counteract with each other, so as to weaken the coupling between the array elements and improve the isolation between the array elements, especially the isolation between 3-5 db array elements.
