发明名称 INDUCTIVE RADIO ANTENNA DEVICE
摘要 PURPOSE:To secure compensation for the disturbance of the transmission/reception signal waveform of the loop antenna by forming the block conductor loop around the loop antenna and then giving the space adjustment between the loop antenna and the block conductor loop. CONSTITUTION:Block conductor loop 4 is provided around loop antenna 3, and loop 4 consists of four pieces of conductors 5, 6, 7 and 8. Then screwing slit 9 is provided to conductors 5 and 6 each, and thus conductors 7 and 8 can move toward the arrow marks. As a result, the space can be adjusted between antenna 3 and loop 4 by moving conductors 7 and 8, thus ensuring compensation for the disturbance of the transmission/reception signal waveform of the loop antenna.
