摘要： Provided is a capacitor coupling type power transmission circuit in which a variation in receiving side voltage due to a variation in capacitance is suppressed to prevent an influence on a variation in load current in a display panel. An insulating board of the display panel is sandwiched by capacitive coupling electrodes formed on each of a transmitting side board and a board of the display panel, thereby forming capacitors. A non-contact transmission is performed by the capacitors. An alternating current voltage signal obtained by electrodes on a display panel side is rectified by a rectifier including diodes. A constant voltage circuit which is a shunt regulator including a diode array in which a resistor and a plurality of diodes are connected in series is provided to maintain a stabilized voltage irrespective of a variation in load in the display panel.

摘要： A small multi-mode antenna in which a single feeding point can be used commonly for multiple frequencies and an RF module using such antenna for use in less-costly and small multimedia wireless apparatus is provided. The antenna is configured such that a single feeding point 4 which is common for multiple frequencies is set up at one end of a radiating conductor 1, a first one-port resonant circuit 2 is connected to the one end thereof, and a second one-port resonant circuit 3 is connected to the other end of the radiating conductor 1. With a conductance component of admittance in view from the feeding point 4 toward free space equaling the characteristic admittance in the RF circuit, a susceptance component of the admittance is canceled out by the resonant circuit 2 connected to the feeding point 4 for multiple frequencies.
