Document Type and Number:
Japanese Patent JP7211543
Kind Code:
B2
Abstract:
An antenna device (101) is configured into an electronic apparatus comprising: a housing that has a conductive frame (10); and a first feeder circuit (1) and a circuit board (20) that are stored in the housing. A radiating element includes a part of the frame (10) and a ground conductor (20G) of the circuit board (20). A part of the frame (10) has a first conductor part (11) and a second conductor part (12). The second conductor part (12) is electrically continuous with the ground conductor (20G) of the circuit board (20). The first conductor (11) has a first end (FE) and a second end (SE). The second end (SE) is disposed close to the second conductor part (12) while the first feeder circuit (1) is connected to the first conductor part (11) via a transformer matching circuit (31). Furthermore, a capacitance part (CP) is formed between the second end (SE) of the first conductor part (11) and the second conductor part (12).
