Abstract

To provide a technology that can suppress the reduction of an antenna gain while maintaining the quality of the design of the exterior furnishing of the antenna.
Provided is an antenna apparatus including: an antenna module that includes a first slot antenna that transmits or receives a first wireless signal, a first feed element that supplies power to the first slot antenna, a second slot antenna that transmits or receives a second wireless signal having a polarization direction orthogonal to a polarization direction of the first wireless signal, and a second feed element that supplies power to the second slot antenna; and a metal plate that includes a first slot, and a second slot a longitudinal direction of which is orthogonal to a longitudinal direction of the first slot.

First claim

The invention claimed is:

1. An antenna apparatus comprising:
an antenna module that includes
a first slot antenna that transmits or receives a first wireless signal,
a first feed element that supplies power to the first slot antenna,
a second slot antenna that transmits or receives a second wireless signal having a polarization direction orthogonal to a polarization direction of the first wireless signal, and
a second feed element that supplies power to the second slot antenna; and

a metal plate that includes
a first slot, and
a second slot a longitudinal direction of which is orthogonal to a longitudinal direction of the first slot, wherein

a shield is mounted on the antenna module, and
a speaker or a microphone is connected to the shield.

2. The antenna apparatus according to claim 1 , wherein the shield is provided with one or more holes.

3. The antenna apparatus according to claim 1 , further comprising:
a third slot a longitudinal direction of which is orthogonal to a longitudinal direction of the first slot.

4. The antenna apparatus according to claim 3 , wherein the first slot is positioned between the second slot and the third slot.

5. The antenna apparatus according to claim 1 , wherein
a size of a slot corresponding to the first slot antenna in a longitudinal direction is substantially ½ a wavelength of the first wireless signal, and a size of a slot corresponding to the second slot antenna in a longitudinal direction is substantially ½ a wavelength of the second wireless signal.

6. The antenna apparatus according to claim 1 , wherein
a short-side direction of the first slot substantially matches a polarization direction of the first wireless signal, and
a short-side direction of the second slot substantially matches a polarization direction of the second wireless signal.

7. The antenna apparatus according to claim 1 , wherein
the metal plate makes up at least a part of a predetermined housing that houses the antenna module.

8. An antenna apparatus comprising:
an antenna module that includes
a first slot antenna that transmits or receives a first wireless signal,
a first feed element that supplies power to the first slot antenna,
a second slot antenna that transmits or receives a second wireless signal having a polarization direction orthogonal to a polarization direction of the first wireless signal, and
a second feed element that supplies power to the second slot antenna; and

a metal plate that includes
a first slot, and
a second slot a longitudinal direction of which is orthogonal to a longitudinal direction of the first slot, wherein

a shield is mounted on the antenna module, and
the shield is mounted on a second substrate positioned on a side opposite to a first substrate, the first substrate being provided with slots corresponding to the first slot antenna and the second slot antenna, respectively, in the antenna module.

9. The antenna apparatus according to claim 8 , wherein
the shield is provided with one or more holes, and
the second substrate is provided with a hole that covers an area facing the holes provided to the shield.

10. The antenna apparatus according to claim 8 , wherein
the shield is provided with one or more holes,
the antenna module includes a third substrate having a dielectric between the first substrate and the second substrate, and
a size of the holes in a polarization direction of the first wireless signal is substantially ¼ a wavelength of the first wireless signal, and a size of the holes in a polarization direction of the second wireless signal is substantially ¼ a wavelength of the second wireless signal.

11. An antenna apparatus comprising:
an antenna module that includes
a first slot antenna that transmits or receives a first wireless signal,
a first feed element that supplies power to the first slot antenna,
a second slot antenna that transmits or receives a second wireless signal having a polarization direction orthogonal to a polarization direction of the first wireless signal, and
a second feed element that supplies power to the second slot antenna;

a shield mounted on the antenna module; and
a speaker or a microphone connected to the shield.

12. The antenna apparatus of claim 11 , wherein
the shield is provided with one or more holes.

13. The antenna apparatus of claim 11 , wherein
the shield is mounted on a second substrate positioned on a side opposite to a first substrate, the first substrate being provided with slots corresponding to the first slot antenna and the second slot antenna, respectively, in the antenna module.

14. The antenna apparatus of claim 13 , wherein
the shield is provided with one or more holes, and
the second substrate is provided with a hole that covers an area facing the holes provided to the shield.

15. The antenna apparatus of claim 13 , wherein
the antenna module includes a third substrate having a dielectric between the first substrate and the second substrate.
