    • An inductor element 10 effectively functions even when formed on a substrate and comprises two upper and lower conductors 1, 2 spirally formed on the front side of a semiconductor substrate 3. The conductors 1, 2 have substantially the same shape. When viewed from the above of the front side of the substrate 3, the two conductors 1, 2 are superposed one on the other almost exactly. Lead wires 6a, 6b are connected to the outer end (outer peripheral end) and the inner end (center end) of the conductor 1, respectively. The outer end of the conductor 1 is connected to the inner end of the conductor 2 through a connection wire 6c. The conductor 1 functions as an inductor conductor and is connected to a circuit provided on the semiconductor substrate 3 through the lead wires 6a, 6b.

    • A plurality of plane antennas 6-1 and 6-2 are embedded in the equipment body section 1, and every time occurrence of reception failure is detected by the internal electronics circuit, switching between the antennas used is established. Spatial diversity through selectively switching and using the plurality of plane antennas 6-1 and 6-2 is performed. Through this, even when reception sensitivity of one antenna in use deteriorates, good reception sensitivity can be gained through switching to another antenna. Thus, this can avoid inconvenience where calls are cut off.
    • 多个平面天线6-1和6-2嵌入在设备主体部分1中,并且每当内部电子电路检测到接收失败的每次发生时,建立所使用的天线之间的切换。 执行通过选择性地切换和使用多个平面天线6-1和6-2的空间分集。 由此,即使使用一个天线的接收灵敏度劣化,也可以通过切换到另一个天线来获得良好的接收灵敏度。 因此,这可以避免呼叫被切断时的不便。
