ANTENNA STRUCTURE AND RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide an antenna structure and a receiver which can enhance the reception sensitivity and can detect an electromagnetic field in multi-axial directions by using a signal detection circuit. SOLUTION: The first antenna section 11 of a first antenna circuit 2 is installed so as to receive an electromagnetic field in the direction of the arrow X at the highest sensitivity. The second antenna section 13 of a 2nd antenna circuit 3 is installed so as to receive an electromagnetic filed in the direction of the arrow Y at the highest sensitivity. The coil 12 of the 1st antenna circuit 2 is inductively coupled with the 2nd antenna section 13 of the 2nd antenna circuit 3. Both terminals of the 2nd antenna section 13 and of a resonance capacitor C2 are connected to the detection circuit 5.
