ABSTRACT:
A signal receiving apparatus includes a receiving circuit board having a signal receiving circuit formed on one side of an insulating substrate, a wide conductive pattern formed on the other side of the insulating substrate that faces a forming position of the signal receiving circuit, and a printed radiating conductor formed on the other side of the insulating substrate deviated from a position that faces the forming position of the signal receiving circuit. In the signal receiving apparatus, an input stage of the signal receiving circuit, an output stage of the printed radiating conductor, and the wide conductive pattern are conductively connected on the receiving circuit board, and received signals are supplied to the signal receiving circuit, by using the printed radiating conductor and the wide conductive pattern as an antenna, through a conductive connection point thereof.
