Abstract
A chip antenna includes a first ceramic substrate, a second ceramic substrate disposed to face the first ceramic substrate, a first patch disposed on the first ceramic substrate to operate as a feed patch, and a second patch disposed on the second ceramic substrate to operate as a radiation patch. One or both of the first ceramic substrate and the second ceramic substrate include a groove, and one or both of the first patch and the second patch is disposed in the groove of the respective first ceramic substrate and second ceramic substrate and protrudes from the groove.
Claims14
A chip antenna comprising:
- a first ceramic substrate comprising a first surface, the first surface having a first groove;
- a second ceramic substrate comprising a second surface disposed to face the first surface of the first ceramic substrate, the second surface having a second groove;
- an interlayer disposed between the first ceramic substrate and the second ceramic substrate;
- a first patch disposed in the first groove on the first surface of the first ceramic substrate and configured to operate as a feed patch;
- and
- a second patch disposed in the second groove on the second surface of the second ceramic substrate and configured to operate as a radiation patch,
- wherein a dielectric constant of the interlayer is less than a dielectric constant of the first ceramic substrate and a dielectric constant of the second ceramic substrate.
A chip antenna comprising:
- a first ceramic substrate comprising a first surface;
- a second ceramic substrate comprising a second surface disposed to face the first surface of the first ceramic substrate;
- an interlayer disposed between the first ceramic substrate and the second ceramic substrate;
- a first patch disposed on the first ceramic substrate and to which a feed signal is applied;
- and
- a second patch disposed on the second ceramic substrate and coupled to the first patch,
- wherein the first surface of the first ceramic substrate comprises a first groove that forms a first step in a thickness direction, and
- wherein the second surface of the second ceramic substrate comprises a second groove that forms a second step in a thickness direction,
- the first patch is disposed in the first groove to fill the first step and the second patch is disposed in the second groove to fill the second step, and
- wherein a dielectric constant of the interlayer is less than a dielectric constant of the first ceramic substrate and a dielectric constant of the second ceramic substrate.
