Abstract

PURPOSE:To enable remote control, by controlling the tuning of the small size antenna circuit having distributed inductance of the curved transmission line by means of digital signal. CONSTITUTION:The antenna circuit consists of a pair of antenna elements 2a, 2b having distributed inductance by bending the transmitted conductor line, variable reactance circuits 4a, 4b having varactor diodes 5a, 5b which are connected to a suitable location of the elements, and impedance adjusting capacitor connected between the power feeding terminals 3a, 3b. The frequency setting code is fed to the terminal 16 of the control circuit 8, this is latched with the latch circuit 15, the output sets the frequency dividing ratio of the frequency divider 13, and DC voltage according to the code appeared at the output of LPF11 is fed to the diodes 5a, 5b. Thus, the resonant frequency of the circuit 1 is changed, at the entire band of specified frequency, the tuning conditions are satisfied, and remote control is made possible by installing the circuit 8 apart from the antenna.
