A microwave module includes a plurality of microwave devices and a microwave module substrate. Each of the plurality of microwave devices exchanges a signal with a corresponding one of a plurality of antenna elements. The microwave module substrate includes a mounting surface on which the plurality of microwave devices are mounted. The microwave module substrate is electrically connected to each of the plurality of antenna elements. The mounting surface is perpendicular to a plane surface on which the plurality of antenna elements are arrayed.

Antenna

In an array antenna apparatus, a first height of top faces of plurality of antenna elements is greater than or equal to a second height of a first top of a first electronic component relative to a first primary surface. The first electronic component is the tallest among one or more electronic components mounted on fourth primary surfaces of one or more first external circuit boards. A third height of a second primary surface is greater than a fourth height of fourth primary surfaces. Accordingly, the array antenna apparatus has good antenna characteristics.

Array antenna apparatus and method for fabricating same

A flexible printed circuit board includes: a base material including a principal face; at least one first wiring pattern disposed on the principal face of the base material and extending along a first direction; and a first member and a second member disposed on the first wiring pattern so as to be spaced from each other in the first direction. In the first direction, the first member and the second member divide the flexible printed circuit board into: a first region located opposite to the second member with respect to the first member in the first direction, a second region located between the first member and the second member, a third region located opposite to the first member with respect to the second member, a fourth region in which the first member is disposed, and a fifth region in which the second member is disposed.
