Package substrate distributed antenna

The invention belongs to the field of antennas of electronic communication technology, and relates to a package substrate distributed antenna. The antenna structure is distributed and designed on a package and a substrate, low-loss interconnection of electromagnetic signals from the package to the substrate is realized through coupling inside the antenna instead of conductor connection, and the package and the substrate are interconnected through electromagnetic coupling. With application of the radiation structure integrated on the substrate, electromagnetic waves coupled by the package are radiated in a specific mode. The package substrate distributed antenna is multiplexed by changing the substrate, and the multiplexing of the package substrate distributed antenna is realized by changing the radiation structure on the substrate without changing the package. The internal interconnection loss of the antenna is reduced, the limitation of the working frequency band of a chip package distributed antenna is solved, the realization of a millimeter wave low-frequency-band distributed antenna becomes possible, more design freedom degrees and flexibility are brought to the design of the millimeter wave antenna, the design period and cost of the millimeter wave integrated antenna are reduced, and the multiplexing of the package design is realized.
