Abstract

PURPOSE:To realize the constitution of the antenna with use of the existing conductor along with the 1st microloop provided near the conductor and with the lumped constant impedance plus the 2nd microloop for feeding purpose. CONSTITUTION:Loop antenna 12 is provided close to existing conductor 11 consisting of the car body, steel pole and others with the space of under one-over- several hundreds of wavelength. Then lumped constant impedance 13 is loaded to part of antenna 12, and at the same time loop antenna 14 for feeding purpose is installed close to conductor 11. Thus loop antennas 12 and 14 form the microloop each. In such antenna device, the feeding is possible from antenna 14 to conductor 11 to avoid the fact that the feeder terminal is provided by cutting off the conductor.
