Abstract
An antenna device includes a first patch antenna, a second patch antenna, and a short circuit plate. The second patch antenna has a resonance frequency different from that of the first patch antenna. The short circuit plate short-circuits one side of the first patch antenna and one side of the second patch antenna to the ground. The length of one side of the short circuit plate, the one side being connected to the one side of the first patch antenna and the one side of the second patch antenna, is shorter than the length of each of the one side of the first patch antenna and the one side of the second patch antenna.
Claims15
An antenna device comprising:
- a first patch antenna;
- a second patch antenna having a resonance frequency different from a resonance frequency of the first patch antenna;
- and
- a short circuit plate that short-circuits one side of the first patch antenna and one side of the second patch antenna to a ground,
- wherein a length of one side of the short circuit plate, the one side of the short circuit plate being connected to the one side of the first patch antenna and the one side of the second patch antenna, is shorter than a length of each of the one side of the first patch antenna and the one side of the second patch antenna.
An antenna module comprising a ground and an antenna device,
- the antenna device including:
- a first patch antenna;
- a second patch antenna having a resonance frequency different from a resonance frequency of the first patch antenna;
- and
- a short circuit plate that short-circuits one side of the first patch antenna and one side of the second patch antenna to the ground,
- wherein a length of one side of the short circuit plate, the one side of the short circuit plate being connected to the one side of the first patch antenna and the one side of the second patch antenna, is shorter than a length of each of the one side of the first patch antenna and the one side of the second patch antenna.
A radio device comprising:
- an antenna device;
- and
- a radio unit that performs transmission or reception of a signal via the antenna device,
- wherein the antenna device includes:
- a first patch antenna;
- a second patch antenna having a resonance frequency different from a resonance frequency of the first patch antenna;
- and
- a short circuit plate that short-circuits one side of the first patch antenna and one side of the second patch antenna to a ground, and
- a length of one side of the short circuit plate, the one side of the short circuit plate being connected to the one side of the first patch antenna and the one side of the second patch antenna, is shorter than a length of each of the one side of the first patch antenna and the one side of the second patch antenna.
