Antenna device and communication device

Disclosed is an antenna device wherein a coupling electrode can be freely disposed without being limited by the position where a transmitting/receiving circuit maintaining excellent connectivity is disposed, while achieving a high production efficiency. The antenna device is provided with: a printed board wherein ground (2) is formed on one surface, and a signal line (3) having signals transmitted thereto is formed on the other surface, with a base material (4) between the ground and the signal line; the coupling electrode (8), which is composed of a conductor having substantially a flat surface, and which performs communication by being coupled, by electromagnetic field coupling, with the electrode of other antenna device disposed on a position facing the coupling electrode; and an electrode post (7) which electrically connects together the signal line (3) formed on the printed board, and the coupling electrode (8) by having the signal line and the printed board at a predetermined interval in the direction of the thickness of the printed board. A connecting terminal section (9) that can be electrically connected with the transmitting/receiving device, which performs signal transmission/reception processing, is formed on one end of the signal line (3), and at least a terminal forming section (1a), which has the connecting terminal section (9) formed thereon, has flexibility in the printed board.

A miniature high-frequency heating power supply for quenching

The invention discloses a miniature high-frequency heating power source for quenching. The miniature high-frequency heating power source for quenching is low in operation cost and high in efficiency. The miniature high-frequency heating power source for quenching comprises a rectifying voltage-regulating system, a high-frequency resonance generating system and a control system. The rectifying voltage-regulating system comprises a rectifier bridge, two smoothing reactors, a positive electrode and negative electrode balance coil and a filter capacitor component. The high-frequency resonance generating system comprises a high-frequency power assembly and a resonance capacitor tank circuit. The high-frequency power assembly comprises four power devices, wherein two of the power devices are connected in parallel to form the positive electrode, the other two power devices are connected in parallel to form the negative electrode, and then the four power devices are connected to the other end of the positive electrode and negative electrode balance coil in parallel. The resonance capacitor tank circuit comprises four capacitors and a short-circuit coil, wherein the capacitor C2 and the capacitor C3 are connected in series and then connected with the positive electrode and the negative electrode of the high-frequency power assembly in parallel respectively, and the capacitor C1 and the capacitor C4 are connected with the positive electrode and the negative electrode of the high-frequency power assembly in series in a one-to-one correspondence mode. The short-circuit coil is connected with the positive electrode and the negative electrode of the high-frequency power assembly in parallel and the midpoint of the short-circuit coil is connected with a connection node between the capacitor C2 and the capacitor C3.
