Description
Technical field
The utility model relates to the adjustable electric wave of the one radiating antenna device again in radio ttransmitter and receiver technical communication field.
Background technology
Radio wave clock is the high-tech product of new generation after quartz electronic clock and watch, and the new mileage of time measurement has been opened up in its appearance.China built up the testing stand that can work 6.5 hours every day in 1999, (50KW all solid-state transmitter, tranmitting frequency 68.5KHZ), within 2000, completed and piloted and part field testing.Within 2007, national time service center is cooperated with Xi'an Gaohua Technology Co., Ltd., 100KW radio controlled timepiece special BPC low-frequency time-code broadcast platform is established at Henan Shangqiu City, thus electric wave signal covers most of China area, received time code can be used to settle the standard the moment, accordingly can the automatic correction clock moment.
But, because the wavelength of long-wave standard electric wave is longer, be thus difficult to propagate into the inside such as building, be arranged in building and the radio wave clock of basement is difficult to receive standard wave, to such an extent as to cannot the auto modification moment.In order to address this problem, the utility model proposes a kind of adjustable electric wave for carrying out moment auto modification radiating antenna device again.To be arranged on the external antenna of large building roof, to receive long-wave standard electric wave, establish cable by this Received signal strength with Shop, be sent to each room of each floor in building, and by being installed on room Inner, miniature antenna device carries out radiation again.
Summary of the invention
The purpose of this utility model provides a kind of adjustable electric wave for carrying out moment auto modification radiating antenna device again, long-wave standard wave radiation is made to enter into each room of each floor in building, meet radio wave clock and receive the needs of standard wave, and its antenna miniaturization, design-adjustable are met the demand of different field settings.
The present utility model is achieved through the following technical solutions:
A kind of adjustable electric wave radiating antenna device again, comprise fixed antenna, adjustable antenna, substrate and diverter switch, fixed antenna and adjustable antenna are arranged on substrate, diverter switch is connected and fixed antenna and adjustable antenna, it is characterized in that: fixed antenna circularizes antenna by framework and coil groups, adjustable antenna is by bar magnet, coil, electric capacity and binding post formed, adjustable antenna is arranged in the framework of fixed antenna, fixed antenna framework is that insulating material is made, coil clockwise direction is outside framework, one end of coil is connected with capacitor, the other end of coil forms loop by binding post external circuit, adjustable antenna horizontal position is arranged in the framework of fixed antenna, the bar magnet of adjustable antenna is wound with coil counterclockwise, adjustable antenna can regulate in the framework of fixed antenna in 360 degree of rotations, formed in parallel with capacitor of coil joins resonant circuit, the coil of fixed antenna loop aerial is connected with capacitor, series resonant circuit is formed by binding post and external circuit, when there being alternation long-wave standard signal to flow through in loop coil, alternating magnetic field will have been produced around coil, due to the diffusion of loop aerial peripheral electromagnetic field, make to produce induced field around ferrite bar magnet and bar magnet coil, and the spreading again of induced field, just more strengthen the magnetic field intensity between loop aerial and ferrite magnetic rod antenna, under the condition of loop coil and the series resonance of capacitor and the parallel resonance of ferrite bar magnet coil and capacitor, final formation resonance, adjustable antenna bar magnet can in the framework of fixed antenna horizontal direction adjustment angle, in the shunt-resonant circuit of magnetic rod antenna coil and capacitor, and link by current-limiting resistance, the series loop of light-emitting diode composition, work as magnetic rod antenna, in the parallel resonance closed-loop path of coil and capacitor, when sensing electric wave signal and produce induction field, understand some induced current and form loop through current-limiting resistance and light-emitting diode, now light-emitting diode bright light, prove that magnetic rod antenna loop has the induced field of electric wave signal with this, also prove electric wave signal radiation function is effectively more simultaneously, the series loop of fixed antenna and capacitor is one group of frequency range diverter switch with the diverter switch be connected between adjustable antenna capacitor shunt circuit, and it act as back-up circuit, first, when there is fault in former loop, by switching over to back-up circuit.Second, when newly-increased frequency is offered at national time service center, select by switch, be switched to another frequency operation (only the capacity of series capacitance and shunt capacitance separately need be elected).Electric capacity due to single ideal capacity is difficult to apolegamy, forms in circuit with multiple shunt capacitance; Magnetic rod antenna in fixed antenna framework, the installation of coil, relative to magnetic rod antenna horizontal level, 0 degree to 20 degree, inclination angle.
The principal character of this antenna assembly is, with the loop aerial that will relatively resonate with the transmission signal launched again, the direction orthogonal with the magnetic direction of this loop aerial tilts some directions, as the mode of magnetic direction, this antenna assembly is configured in this loop aerial, comprise the magnetic rod antenna resonated with transmission signal, make electric field strength become roughly non-direction antenna assembly by loop aerial and magnetic rod antenna.
Owing to being provided with magnetic rod antenna in loop aerial, and bar magnet adopts high permeability material to make, when flowing through electric wave signal in loop aerial, due to electromagnetic induction principle, a large amount of induced fields is produced around magnetic rod antenna, and this induced field direction is consistent with loop aerial magnetic direction, form resonance.Along with the aggravation of resonance, field intensity constantly increases, but whether magnetic density distribution is even, proves by experiment to have depression points on magnetic field distribution figure.Because magnetic rod antenna receiving feature has directivity, for this adjusts slightly to the direction of magnetic rod antenna and gradient, just can change magnetic direction, play and make up magnetic density skewness and the effect causing depression points.Thus combination change in magnetic field between loop aerial and magnetic rod antenna can be obtained, the Best Point Position of resonance frequency generation electric field strength.
