Abstract
A ground conductor (1) having slots (2a to 2g) for radiating electromagnetic waves, a ground conductor (3) in which cavities (4) recessed in a direction away from the ground conductor (1) is formed in positions opposite to the slots (2a to 2g) of the grounding conductor (1), and central conductors (5a, 5b, 6a to 6c, 7a, and 7b) arranged in positions overlapping with the slots (2a to 2g), respectively, between the ground conductor (1) and the ground conductor (3) are provided. The central conductors (5a, 5b, 6a to 6c, 7a, and 7b) are arranged such that the ground conductor (1) is closer to them than the ground conductor (3).
Claims6
An antenna device comprising:
- a first ground conductor having a slot for radiating an electromagnetic wave;
- a second ground conductor on which a cavity recessed in a direction away from the first ground conductor is formed in a position opposite to the slot of the first ground conductor;
- a first central conductor arranged between the first ground conductor and the second ground conductor in a position overlapping with the slot;
- a third ground conductor configured to disturb an electromagnetic field between the first ground conductor and the second ground conductor, wherein one end of the third ground conductor is conductively connected to the first ground conductor or the second ground conductor, and another end of the third around conductor is proximate to the other of the second ground conductor or the first around;
- and
- coupling-suppressing conductors arranged parallel to and on both sides of the first central conductor, each coupling-suppressing conductor having one end electrically connected to the first ground conductor and having another end electrically connected to the second ground conductor.
