Abstract
In an antenna in package structure, a plurality of supporting blocks spaced apart from each other are disposed between a first substrate and a second substrate, and an antenna cavity is formed between every two adjacent supporting blocks. Therefore, a height of the supporting block determines a height of the antenna cavity. The supporting blocks spaced apart from each other are located between the first substrate and the second substrate, and at least one of the first substrate or the second substrate adheres to the supporting blocks spaced apart from each other using an adhesive layer.
