Abstract: 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.

Abstract: 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.

Abstract: An irreversible circuit element that can reduce manufacturing costs by preventing faults that lead to product defects includes a magnetic body, a magnetic body securing casing, and a magnet. The magnetic body securing casing is arranged so as to surround the magnetic body. The magnet is arranged on one side of the magnetic body. The magnetic body securing casing includes a first electrode on one casing main surface arranged on the one side, a second electrode on the other casing main surface arranged on the other side opposite to the one side, and a through-conductor that passes through the magnetic body securing casing and electrically connects the first electrode to the second electrode. The first electrode is connected to a first wiring arranged on the one side of the magnetic body.

Abstract: An array antenna apparatus includes: a wiring substrate having a plurality of fed patch antennas and a plurality of active element circuits electrically connected to the plurality of fed patch antennas, respectively; and a plurality of antenna substrates each having a parasitic patch antenna. The plurality of antenna substrates are joined onto one wiring substrate. Thereby, it becomes possible to provide an array antenna apparatus that can be reduced in size and has excellent antenna characteristics.
