Description
Technical field
The utility model relates to a kind of short-wave antenna, is specifically related to a kind of shortwave coil antenna.
Background technology
Along with the fast development of mobile communication equipment, the antenna of communication all needs could work by relay station on the market, and in mountain area, zones such as Gobi desert or oceans, short-wave antenna on the market all can not meet communication need at present.In addition, the short-wave antenna of application also exists the narrow phenomenon of frequency range on the market at present, and its volume is relatively large for the wide short-wave antenna of some frequency ranges, and manufacturing cost is higher, therefore, be necessary to provide a kind of simple in structure, frequency range is wide and manufacturing cost is relatively low short-wave antenna.
The utility model content
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides that a kind of frequency range is wide, the shortwave coil antenna of low cost of manufacture.
The utility model is achieved through the following technical solutions: a kind of shortwave coil antenna, comprise mounting bracket, be arranged at the resonant ring on mounting bracket, described shortwave coil antenna also comprises coupling loop, described coupling loop is arranged on described resonant ring by connector, also is connected with coaxial cable on described coupling loop.
Further, also be provided with the resonant capacitance that can regulate resonant parameter on described resonant ring.
Preferably, described resonant capacitance is arranged at the top of resonant ring, and described coupling loop is arranged at the bottom of resonant ring, is positioned at the below of resonant capacitance.Described resonant capacitance and coupling loop are on same straight line.
Described resonant capacitance is provided with the adjusting screw thread, this adjusting synchronous machine that has been threaded, and described synchronous machine is connected with control device, can control synchronous machine by control device and reach the purpose of regulating the resonant capacitance resonant parameter.
Compared with the prior art, the utlity model has novelty simple in structure, volume little and manufacture simple, the advantage such as frequency range is wide.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1-resonant ring, 2-resonant capacitance, 3-coupling loop, 4-coaxial cable, 5-mounting bracket, 6-connector.
Embodiment
Understanding for the ease of those skilled in the art, be described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of shortwave coil antenna, comprise mounting bracket 5, resonant ring 1 and coupling loop 3, and described resonant ring is arranged on mounting bracket, and described coupling loop is arranged on described resonant ring by connector 6, is connected with coaxial cable 4 on described coupling loop.Also be provided with the resonant capacitance 2 that can regulate resonant parameter on described resonant ring.Described resonant capacitance is provided with the adjusting screw thread, this adjusting synchronous machine that has been threaded, described synchronous machine is connected (described adjusting screw thread with control device, synchronous machine, control device does not all indicate in the drawings), can control synchronous machine by control device and reach the purpose of regulating the resonant capacitance resonant parameter.
Preferably, described resonant capacitance is arranged at the top of resonant ring, and described coupling loop is arranged at the bottom of resonant ring, be positioned at resonant capacitance under, described resonant capacitance and coupling loop are on same straight line.
The shortwave coil antenna that the utility model provides, by adopting the loop design of resonant ring and coupling loop, and can regulate according to actual needs the resonant parameter of resonant capacitance, can make it work in the 1-30MHz band limits, have that working frequency range is wide, novel structure, manufacture the advantages such as simple and low cost of manufacture.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite that does not break away from inventive concept of the present utility model, any apparent replacement is all within protection range of the present utility model.
