Abstract
The utility model discloses a kind of simple adjustable height powered radio short wavelength emissions small loop antenna, it is related to radio short-wave antenna, the more particularly to adjustable high power short wavelength emissions antenna of radio.The antenna is made of metal tube 1, cable 2,3 three parts of feed section.There is dielectric insulation layer between metal tube 1 and cable 2, two parts can form capacitance, and cable 2 can be moved along metal tube 1, and capacitance can follow change when mobile, so may be formed at antenna tunable in the range of certain frequency.The antenna has two big advantages, and one can be easily reached high power, and two is simple in structure.
Description
Technical field
A kind of radio short wavelength emissions antenna is the utility model is related to, belongs to radio communication field.
Background technology
Existing ham radio shortwave loop transmit antenna has radiation ring and external tunable capacitor, is used in high power
When external tunable capacitor pressure voltage require it is very high, general tunable capacitor be all extremely difficult to it is very high pressure-resistant, in practical application
In, existing loop aerial high power using when tunable capacitor can all be made big, have impact on the convenience of antenna installation.It is existing
Some small rings of shortwave have in actual use it is pressure-resistant not enough, volume structure is big, not the deficiencies of Portable belt.
Utility model content
The technical problem to be solved by the utility model is to for the deficiency in above-mentioned existing technology, from brand-new angle
Degree proposes a kind of production method of small loop antenna, and the especially acquisition of the tunable capacitor of high voltage, directly utilizes and form antenna
Radiate a pole of the metal surface of ring as tunable capacitor so that the structure of antenna more simple and compact, makes more convenient.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of simple adjustable high power without
Line electricity short wavelength emissions small loop antenna, it is characterised in that curve annular with metal tube 1, both ends are not closed, then are worn in metal tube 1
Enter a cable 2, the crust of cable 2 is insulation, and cable 2 can move in metal tube 1.Applied metal pipe 1
Surface forms a pole of tunable capacitor, and cable 2 is another pole of tunable capacitor.It is electric when cable 2 is moved along metal tube 1
The capacity of appearance is changed.The pressure voltage of capacitance is determined by the dielectric withstanding voltage in the insulation voltage and metal tube 1 of cable 2.
The tunable capacitor of such a high voltage is just formd by the inner wall and cable 2 of metal tube 1.The resonance point of small loop antenna is by gold
The movable length of the length of category pipe 1 and the length and cable 2 of pipe inner cable line 2 in metal tube 1 determines.Removal cable
Line 2 makes capacitance change, capacitance variations, is the resonance point change of antenna, is thus simply and easily made that a height is resistance to
The adjustable small loop antenna of pressure.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Description of reference numerals：
1- metal tubes；2- cables；3- feed structures.
Embodiment
As shown in Figure 1, antenna is made of metal tube 1, cable 2,3 three parts of feed structure.
