Abstract
A small antenna comprises a planar antenna element, and a resin molded body integrally molded with the antenna element, and the resin molded body has a thin part and a thick part on both sides of the antenna element, and a gate portion at a resin molding is provided to the thin part.
Claims25
A small antenna comprising:
- a planar antenna element;
- and
- a resin molded body integrally molded with said antenna element, wherein
- said resin molded body has a thin part and a thick part on both sides of said antenna element, and a gate portion at a resin molding is provided to the thin part.
1 more element
A small antenna comprising:
- a planar antenna element;
- a resin molded body integrally molded with said antenna element;
- and
- a hole formed to said antenna element.
1 more element
A small antenna comprising:
- an antenna element;
- and
- a resin molded body in which said antenna element is embedded or which is accumulated, said antenna element having a terminal extended to an outside of said resin molded body, wherein
- said terminal comprises a narrowed portion with narrow width of a conductor at a base thereof, and
- said narrowed portion is bent at an outside of said resin molded body.
2 more elements
A manufacturing method of a small antenna comprising:
- setting an antenna element to place the antenna element between a first mold and a second mold of the mold;
- and
- integrally molding a resin molded body to embed the antenna element by injecting the resin to the mold, wherein
- a depth of a cavity of the first mold is shallower than a depth of a cavity of the second mold, and
- a gate portion is provided to the first mold.
2 more elements
A manufacturing method of a small antenna comprising:
- setting an antenna element in a mold;
- performing injection molding by injecting a resin which is a dielectric material in said mold;
- and
- ejecting a resin molded body by striking an ejector pin to the resin molded body, when the mold is opened and the resin molded body after the injection molding is taken out, wherein
- said resin molded body has the surfaces whose thickness are different at both sides of the antenna element, and
- ejecting including striking the ejector pin to a thicker surface of said resin molded body and ejecting said resin molded body.
3 more elements
A manufacturing method of a small antenna comprising:
- setting an antenna element in a mold;
- performing injection molding by injecting a resin which is dielectric material in said mold;
- and
- ejecting a resin molded body by striking an ejector pin to the resin molded body, when the mold is opened and the resin molded body after the injection molding is taken out, wherein
- ejecting includes striking the ejector pin to a position where a part to which said resin molded body is picked up is avoided and ejecting the resin molded body.
2 more elements
A manufacturing method of a small antenna comprising:
- setting a part of an antenna element to be sandwiched and contacted with parting faces of a mold;
- and
- injecting a resin in the mold, wherein
- setting includes setting the antenna element to form a space in a part where the antenna element is not placed and faced in the parting faces.
1 more element
A manufacturing method of a small antenna comprising:
- setting an antenna element by placing at least a part between parting faces of the mold;
- and
- injecting a resin in the mold and performing a molding, wherein
- a plurality of support parts extended to an outside to at least two opposite sides in the antenna element are integrally formed, and
- setting includes setting the antenna element to place the plurality of support parts between the parting faces of the mold in the parting faces, and form a space in a part where the plurality of support parts between the parting faces of the mold is not placed.
