Description

technical field [0001] The invention belongs to the technical field of electronic packaging, and in particular relates to an integrated packaging antenna and a packaging method thereof. Background technique [0002] With the rapid development of wireless communication technology, especially the wide application of mobile communication and wireless local area network, the encapsulation requirements for radio frequency transceiver systems are also getting higher and higher, requiring small volume, low cost, and high integration. [0003] For the interconnection of antennas and systems, it is usually implemented after separate design and assembly. Although this is helpful for the separate design of each antenna and system, the interconnection loss between the antenna and the module will greatly increase the size and cost of the system. Contents of the invention [0004] The purpose of the present invention is to provide an integrated package antenna and its packaging method, ...
