  • Patent number: 10840581
    Abstract: An electronic package is provided with a first substrate having a first antenna portion that is stacked on a second substrate having a second antenna portion via an antenna component. During a packaging process, a gap between the first substrate and the second substrate is held constantly by the antenna component. At the same time, the antenna component is regarded as a third antenna portion of the electronic package. The performance of the antennae is not adversely affected by the antenna component despite the fact that the antenna component is in close proximity to the first and second antenna portions.
