Chip antenna module array and chip antenna module

A chip antenna module array, comprising:

• a connection member comprising:
• wiring vias spaced apart from each other and extending in a vertical direction;
• and
• at least one connection member feed line electrically connected to a corresponding wiring via among the wiring vias, and extending in a horizontal direction;
• and
• chip antenna modules spaced apart from each other and mounted on an upper surface of the connection member,
• wherein each of the chip antenna modules comprises:
• a first patch antenna dielectric layer;
• a feed via extending through the first patch antenna dielectric layer;
• and
• a patch antenna pattern disposed on an upper surface of the first patch antenna dielectric layer and configured to be fed from the feed via, and
• wherein at least one of the chip antenna modules comprises:
• a ground pattern disposed on a lower surface of the first patch antenna dielectric layer;
• a chip-antenna feed line including first, second, and third parts connected to each other in series, disposed such that the second part is disposed on a lower surface of the ground pattern, and electrically connecting the at least one connection member feed line and the feed via to each other;
• a first feed line dielectric layer disposed on a lower surface of the second part;
• and
• a solder layer disposed on a lower surface of the first feed line dielectric layer and configured to support mounting of at least one of the chip antenna modules.
