Abstract:
A first metal frame (6) is arranged along the outer surface of an upper part of a case (2), and has a length that extends approximately halfway around the case (2). A second metal frame (7) is arranged along the outer surface of a lower part of the case (2), and has a length that extends approximately halfway around the case (2). One end (6a) of the first metal frame (6) is connected to a power supply terminal (9) that is connected to a matching circuit unit (5) on a circuit board (3), while the other end (6b) is connected to a ground (3G) of the circuit board (3) via a first grounding terminal (10). One end (7a) of the second metal frame (7) is connected, near the power supply terminal (9), to the ground (3G) of the circuit board (3) by a second grounding terminal (11), while the other end (7b) is positioned near the first grounding terminal (10) as an open end. The electrical lengths of the first and second metal frames (6, 7) are configured to be approximately equal.
