Abstract
Abstract An earthing conductor is disposed on the reverse of a print board, and a signal process circuit section including a transmit-and-receive circuit is disposed on the right side of the board. A loading coil is mounted on the right side of the board across a print pattern of the signal process circuit section and a print pattern of an antenna. A vertical portion of the antenna projects from the print pattern of the antenna on the print board, and a horizontal portion of the antenna horizontally extends from a top end of the vertical portion in parallel with the print board.
