Abstract
An antenna substrate includes a cap substrate including first antenna conductors arranged lengthwise and crosswise on a first insulating layer facing each other, and a first connection pad on the outer peripheral edge of the first insulating layer's lower surface; a frame substrate including a second connection pad on an outer peripheral edge of a second insulating layer's upper surface and a third connection pad on an outer peripheral edge of the second insulating layer's lower surface; and a base substrate including a plurality of second antenna conductors arranged on a third insulating layer's upper surface and a fourth connection pad on an outer peripheral edge of the third insulating layer's upper surface. The base, frame and cap substrates are layered in this order. First opening portions in the second insulating layer have an outer periphery located radially outward from the first antenna conductor's outer periphery in a top view.
