ANTENNA

摘要

PURPOSE:To transmit signals to a remote place precisely with the small amount of electric power by folding an antenna with the specific wavelength of a carrier at least at the center part and using one end of the antenna as a power supplying terminal. CONSTITUTION:The antenna having 3/4 wavelength of the carrier is folded at the intermediate point (b) and a telemeter device (e) is connected to one end of the antenna. Electric power is supplied to the antenna through the telemeter device (e). Current from the point (a) to the point (b) is added to current from the point (b) to the point (c) by folding the antenna at the intermediate point, so that radiation power is increased and single directivity is obtained.
