ANTENNA DEVICE AND COMMUNICATION TERMINAL DEVICE |
摘要 |
<p>A rectangular spiral-shaped coil conductor (CW) is formed on a flexible substrate (10). A rectangular aperture is made in the central portion of the area where the coil conductor (CW) is formed, and a magnetic core (1) is disposed in the aperture. The coil conductor (CW) includes a first conductor portion (11) adjacent to a first main surface (MS1) of the magnetic core (1) and a second conductor portion (12) adjacent to a second main surface (MS2) thereof. The magnetic core (1) and the coil conductor (CW) form an antenna coil (21). A circuit substrate (20) includes a ground electrode formation area (GA) and a ground electrode non-formation area (NGA). The antenna coil (21) is mounted on the ground electrode non-formation area (NGA) of the circuit substrate (20) with the first main surface (MS1) of the magnetic core (1) facing the circuit substrate (20).</p> |
