Abstract

A disclosed antenna apparatus includes: a punched out antenna element made of a sheet metal; a punched out ground element made of a sheet metal, the ground element facing the antenna element; and a surface mount type coaxial connector mounted across the antenna element and the ground element.

Claims

1. An antenna apparatus, comprising:

a punched out antenna element made of sheet metal;

a punched out ground element made of sheet metal, the ground element being coplanar with, and spaced by a gap from, the antenna element, wherein two sides of the antenna element opposing a side of the ground element are each tilted by a non-zero angle with respect to an axis orthogonal to the side of the ground element; and

a surface mount type coaxial connector positioned to extend across the gap and interconnect the antenna element and the ground element.

2. An antenna apparatus comprising:

a punched out antenna element made of sheet metal;

a punched out ground element made of sheet metal, coplanar with and spaced by a gap from the antenna element;

a surface mount type coaxial connector positioned to extend across the gap and interconnect the antenna element and the ground element; and

a plate-like synthetic resin portion molded onto and encasing the antenna element and the ground element, except for the coaxial connector, and fixing the antenna element and the ground element together.

3. An antenna apparatus, comprising:

a punched out antenna element made of sheet metal;

a punched out ground element made of sheet metal, coplanar with and spaced by a gap from, the antenna element;

a surface mount type coaxial connector positioned to extend across the gap and interconnect the antenna element and the ground element; and

a plate-like synthetic resin portion molded onto and encasing the antenna element and the ground element and having an internal recess into which the coaxial connector extends, the synthetic resin portion fixing the antenna element and the ground element together.
