EMC shield apparatus

摘要

An EMC shield apparatus has an antenna including a conductor part, a substrate, which is arranged to be separated from the antenna, and on which a circuit that processes a signal supposed to be transmitted by the antenna or a signal received by the antenna is mounted, and a shielded conductor that is connected to the conductor part of the antenna such that a closed loop circuit that surrounds the substrate is formed, and covers periphery of the substrate together with the antenna in a steric manner, keeping a distance from the substrate.

1. An EMC shield apparatus comprising:
an antenna having a bandpass filter characteristic and including a conductor part; a substrate, which is arranged to be separated from the antenna, and on which a circuit that processes a signal to be transmitted by the antenna or a signal received by the antenna is mounted, said substrate including a coil configured to transmit or receive signals between the antenna and circuit; and a shielded conductor that is connected to a ground potential and to the conductor part of the antenna such that a closed loop circuit that surrounds the substrate is formed, and covers a periphery of the substrate together with the antenna, keeping a distance from the substrate, wherein a signal is transmitted from the antenna to the substrate in a non-contact manner, and the substrate transmits a signal to the antenna in a non-contact manner.
