Antenna board

摘要

The antenna board of the present invention includes: a dielectric board where a plurality of dielectric layers are laminated, a ground conductor layer, a strip conductor, a first patch conductor, a second patch conductor, a third patch conductor, and a penetration conductor. The first patch conductor, the second patch conductor, and the third patch conductor are electrically independent of each other. The penetration conductor includes at least two penetration conductors aligned adjacent to each other in the extending direction of the strip conductor.

1. An antenna board comprising:
a first dielectric layer; a strip conductor disposed on a top surface of the first dielectric layer so as to have an end part in a central part of the first dielectric layer, extending in one direction from an outer peripheral edge towards the end part; a ground conductor layer disposed on a bottom surface side of the first dielectric layer; a second dielectric layer laminated on a top surface side of the first dielectric layer and the strip conductor; a first patch conductor disposed on a top surface of the second dielectric layer so as to cover a position of the end part of the strip conductor; a third dielectric layer laminated on the second dielectric layer and the first patch conductor; a second patch conductor disposed on a top surface of the third dielectric layer so that at least part of the second patch conductor covers a position where the first patch conductor is formed, being electrically independent; a fourth dielectric layer laminated on the third dielectric layer and the second patch conductor; a third patch conductor disposed on a top surface of the fourth dielectric layer so that at least part of the third patch conductor covers a position where the second patch conductor is formed, being electrically independent; and at least two penetration conductors connecting the end part of the strip conductor and the first patch conductor by penetrating the second dielectric layer, wherein the at least two penetration conductors align adjacent to each other in the one direction.
