Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2023048294
Kind Code:
A
Abstract:
To provide an antenna device capable of adjusting the performance of a desired frequency band while suppressing influences on antenna performance outside the desired frequency band, associated with double resonance.SOLUTION: An antenna device comprises a substrate main body 2, a ground pattern G0, a first element 3 and a second element 4. The ground pattern has a ground principal surface part G1 and a ground connection part G2. The first element has: a first extending part E1 connected with a feeding point; a second extending part E2; and a third extending part E3. The second element has a fourth extending part E4, a fifth extending part E5, and a sixth extending part E6. The ground connection part has: a convex GND part G3 arranged so as to be opposed to the first extending part, being protruded convexly toward the first extending part; and an intermediate connection part G4 arranged so as to be opposed to the sixth extending part, extending from the ground principal surface part to the convex GND part.SELECTED DRAWING: Figure 1
