摘要： PURPOSE:To eliminate effectively a disturbing wave incoming from an optional angle with one set of antenna and to ensure stably a gain of a required receiving wave in the wave incoming direction, by arranging plural elements in parallel with each other and obliquely to an arm. CONSTITUTION:A reflector 11, a radiator 12 and each element of plural wave directors 13 are arranged in parallel with each other and obliquely to the arm 14. The center of the radiator 12 is taken as the original of coordinates, a line prolonged from the elements is taken as phi=90 deg. and the orthogonal direction is taken as phi=0 deg.. Further, the angle of arrangement of the elements to the arm 14 is taken as theta and the direction of main beam is taken as phi=theta-alpha. Thus, the disturbing wave is eliminated over a wide range with one set of antenna in this way and the phase of feeding is not required to be changed. Further, the drop in power gain in the direction of main beam is not much.

摘要： PURPOSE:To vary transmission electric power by converting a signal received at some point into a light signal corresponding to its signal electric field intensisty and feeding it back to a transmitter, and holding the signal intensity of the feedback signal constant. CONSTITUTION:The transmission electric power P from the transmitter 1 is matched and fed to a monopole type transmitting antenna 13. This transmitting antenna 13 is installed at antenna height which is extremely close to 1/10 wavelength. A transmit signal radiated by this transmitting antenna 13 is received by a loop type receiving antenna 14 at an well open remote reception point and the receive signal voltage ER is supplied to a receiver 15. This receiver 15 amplifies and detects the receive signal voltage ER, converts the detected signal logarithmically, and performs A/D conversion. This receiver 15 supplies the receive digital voltage signal E1 obtained by the A/D conversion of an electrooptic converter (E/O)16 to obtain a light signal OR by conversion, and the signal is transmitted and fed back to the optoelectric converter (O/E)12 of the transmitter 11 by optical fiber communication or space transmission.

摘要： PURPOSE:To attain the stable reception among areas having the same level of electric power at the middle part between adjacent broadcast stations in a synchronizing broadcast system, by synthesizing the outputs of monopole antenna and multi-turn loop antennas formed on ferrite bars. CONSTITUTION:A whip antenna 11 is used to receive the electric fields, and bar antennas 12 and 13 formed by winding coils round ferrite bars are set orthogonal to each other to receive the magnetic fields. The outputs of antennas 12 and 13 are connected in parallel by an impedance matching box 14, and a capacitance is used to secure the parallel tuning between the outputs of both antennas 12 and 13 and the reactance of a loop antenna. This induced voltage is dropped by a transformer, etc. to secure the matching of impedance and then synthesized with the output of the antenna 11 by a synthesizer 15. Then this synthetic output is led to a receiver 16.
