    • Stable receiving is realized by a simpler receiver constitution. When a hand of a human body is made to face a panel section (201), the electric field around the human body is coupled to a sensor electrode (2122) of a coil sensor (212) through a receiving electrode (211) of the panel section (201), and an AC current is generated in the sensor electrode (2122). The AC current induces a magnetic flux corresponding to the intensity of the electric filed around the human body in the center hole of a coil (2121). In response to the variation of the magnetic flux, a current flows through the coil (2121) and converted into a voltage signal by a current detecting circuit (2124) of the coil sensor (212). The voltage signal is sent to a demodulator (22) as a received signal. As a result, a received signal following up the electric field around the human body, that is, a transmission signal applied to the human body by a transmitter (1) is obtained.
    • 通过更简单的接收机结构实现稳定的接收。 当人体的手被制成面对面板部分(201)时,人体周围的电场通过线圈传感器(212)的接收电极(211)耦合到线圈传感器(212)的传感器电极(2122) 面板部(201),在传感器电极(2122)中产生交流电流。 AC电流引起对应于线圈(2121)的中心孔中的人体周围的电场的强度的磁通量。 响应于磁通量的变化,电流流过线圈(2121)并被线圈传感器(212)的电流检测电路(2124)转换成电压信号。 电压信号作为接收信号发送到解调器(22)。 结果,获得跟随人体周围的电场的接收信号,即,由发射机(1)施加到人体的传输信号。

    • PURPOSE: An LC filter circuit, a laminated LC composite component, a multiplexer and a radio communication device are provided to be capable of designing an attenuation pole without the center frequency band being varied and considerably reducing the size of the laminated LC composite. CONSTITUTION: A laminated LC composite component(1) is provided with insulator sheets(2,3,4,5,6,7,8) including coil-shaped conductor patterns(9,10), via-holes(11a,11b,12a,12b,15), capacitor electrode patterns(13,14,15,16,17,18), and a ground electrode pattern(19), respectively. The insulator sheets are manufactured preferably by mixing dielectric powder or magnetic powder with a binder or other suitable material, and forming the mixture into a sheet. The thickness of the sheet(5) having the via-hole(15), is preferably larger compared to the other sheets. The thickness of the sheet(5) is attained by laminating a plurality of sheets each having the same thickness as that of a sheet(2), or by using one sheet having a large thickness.
