Antenna packaging solution

A method for fabricating an antenna package comprising:

• providing a first and second antenna substrate, each antenna substrate with a respective array of antenna elements disposed on a respective first surface;
• placing a plurality of stand-off balls on the first surface of the first antenna substrate, a first sub-plurality of the stand-off balls placed at positions in a peripheral region of the first substrate and a second sub-plurality of the stand-off balls at interior positions between antenna elements;
• dispensing an adhesive on the first surface of one of the antenna substrates at a plurality of discrete selected locations, wherein a first location of the discrete selected locations is a peripheral region and a second location of the discrete selected locations is at interior positions between antenna elements;
• and
• joining the first antenna substrate to the second antenna substrate in a force capping process using an adhesive cure process, wherein the plurality of stand-off balls provide a plurality of controlled gap spacers and the dispensed adhesive forms a plurality of adhesive pillars joining the first and second antenna substrates.
