Abstract
Official abstract text for this publication.
A multiband antenna includes a first antenna unit ( 10 ) and a second antenna unit ( 20 ). The first antenna unit ( 10 ) includes a first antenna pattern ( 11 ) formed of a conductor and a first substrate ( 12 ) formed of a dielectric, for holding the first antenna pattern ( 11 ). The second antenna unit ( 20 ) includes a second antenna pattern ( 21 ) formed of a conductor and a second substrate ( 22 ) formed of a dielectric having a dielectric constant different from the dielectric constant of the first substrate ( 12 ), for holding the second antenna pattern ( 21 ). In the multiband antenna, by injection molding the second substrate ( 22 ) with the first antenna unit ( 10 ) and the second antenna pattern ( 21 ), which being insert components, the first antenna unit ( 10 ) and the second antenna unit ( 20 ) are integrated.
First claim
Opening claim text (preview).
The invention claimed is: 1. A multiband antenna, comprising: a first antenna unit comprising: a first antenna pattern formed of a conductive plate; and a first substrate formed of a dielectric, for holding the first antenna pattern; and a second antenna unit comprising: a second antenna pattern formed of a conductive plate separated from the first antenna pattern; and a second substrate formed of a dielectric having a dielectric constant different from the dielectric constant of the first substrate, for holding the second antenna pattern, wherein the first antenna pattern is provided only on a surface of the first substrate, and the second antenna pattern is provided only on a surface of the second substrate, wherein the first substrate of the first antenna pattern is covered with the second substrate of the second antenna pattern from three directions orthogonal to each other so that the multiband antenna is substantially in the shape of a rectangular parallelepiped as a whole, and wherein the first antenna pattern is perpendicular to the second antenna pattern. 2. The multiband antenna according to claim 1 , wherein the first antenna unit is formed by injection molding the first substrate with the first antenna pattern, the first antenna pattern being an insert component. 3. The multiband antenna according to claim 2 , wherein the first substrate and the second substrate are formed through double molding of resins having different dielectric constants. 4. A method of manufacturing a multiband antenna, the multiband antenna comprising: a first antenna unit comprising: a first antenna pattern formed of a conductive plate; and a first substrate formed of a dielectric, for holding the first antenna pattern; and a second antenna unit comprising: a second antenna pattern formed of a conductive plate separated from the first antenna pattern; and a second substrate formed of a dielectric having a dielectric constant different from the dielectric constant of the first substrate, for holding the second antenna pattern, the first antenna pattern being provided only on a surface of the first substrate, and the second antenna pattern being provided only on a surface of the second substrate, the first substrate of the first antenna pattern is covered with the second substrate of the second antenna pattern from three directions orthogonal to each other so that the multiband antenna is substantially in the shape of a rectangular parallelepiped as a whole, and wherein the first antenna pattern is perpendicular to the second antenna pattern, the method comprising the steps of: forming the first antenna unit; and forming the second antenna unit and integrating the first antenna unit and the second antenna unit by injection molding the second substrate with the first antenna unit and the second antenna pattern, the first antenna unit and the second antenna pattern being insert components. 5. The method of manufacturing a multiband antenna according to claim 4 , wherein the forming the first antenna unit comprises injection molding the first substrate with the first antenna pattern, the first antenna pattern being an insert component. 6. The method of manufacturing a multiband antenna according to claim 5 , further comprising forming the first substrate and the second substrate through double molding of resins having different dielectric constants.
