Abstract

PURPOSE:To obtain the transmitter of equal quality by means of etching, by forming the earth wire of antenna and the inner conductor of semicoaxial resonator on the printed board. CONSTITUTION:The upper conductor pattern 8a, lower conductor pattern 8b are provided on the printed board 8 with a given shape by means of etching. A part of the conductor pattern is covered with the upper conductor plate 9a, lower conductor plate 9b to form the semicoaxial resonator 9 taking the conductor pattern as the center conductor. The metal plate 12 is fixed with the screw 11 and the screw 11 is fitted to the dielectric 10. 1 is the antenna radiation part. On the printed board 8, the oscillation circuit using the resonator 9 is provided and various information can be transmitted with radio by modulating the oscillation circuit. The transmission freuquency can be decided with the pattern length of the resonator 9.
