Traditional medium wave radiating antenna, floor space is big, and maintenance difficulty is big, and the additional potential anchor is many, poor safety performance, many defectives such as fund input is big; People press for development a kind of safe and reliable stable, floor space is little, without the antenna of additional potential anchor, and have same or be better than the novel medium wave radiating antenna of conventional pull wires formula antenna function and effect.
Three, utility model content
The purpose of this utility model is poor in order to solve existing conventional pull wires medium wave radiating antenna wind resistance, safeguards inconvenience, draws anchor many, and floor space is very big, sets up problems such as complexity, thus a kind of new technical scheme that proposes.
For achieving the above object, the utility model can be achieved through the following technical solutions:
A kind of novel wide-band tower medium wave radiating antenna of supporting oneself, it is on the antenna body column foot high frequency insulator to be installed, medium wave radiating antenna is installed in upper end at high frequency insulator, be connected with contact tube between medium wave radiating antenna and day accent network, the shape of medium wave radiating antenna is to be composed of a fixed connection by triangular cone and top load cone shape; Described top load cone is the polygon inverted pyramidal structures, and is fixedly connected on the upper end of triangular cone dorsad.
The triangular cone is three forward cone structures, and the length of side is 9.716 meters; The top load cone is the hexagon inverted pyramidal structures, and its cone angle is between 70 °-120 °, and the awl length of side is 2 meters; The tower body total height is 76 meters-110 meters.
The utility model antenna is compared the innovative point that is had with existing conventional pull wires antenna: one, simple in structure, the area that keeps out the wind is little, wind loading rating is strong, long service life; Two, floor space is little, sets up and easy to maintenance, cheap for manufacturing cost, the convenience of drawing materials; Three, adopt base drive, all participate in the signal emission more than bottom insulation, form real transmitting antenna; Four, adopting the tower projectile configuration of supporting oneself, is again the bipyramid transmitting antenna, and the antenna feed impedance rate of change is little, and the beamwidth of antenna is wideer, has improved the radiation efficiency of antenna; Five, owing to adopt the top load projectile configuration, can improve the radiation resistance of antenna, reduce reactive component, expand the beamwidth of antenna, make the radiation efficiency of antenna higher, and can satisfy the transmission requirement of full frequency band digital broadcast signal fully.
Four, description of drawings
Accompanying drawing 1 is a kind of embodiment overall structure of the utility model schematic diagram;
Accompanying drawing 2 is amplification front elevations of top load cone 4 in the accompanying drawing 1;
Accompanying drawing 3 is plan structure figure of accompanying drawing 2.
Five, embodiment
Now with specific embodiment the utility model is described in further detail in conjunction with the accompanying drawings:
A kind of novel wide-band tower medium wave radiating antenna of supporting oneself, it is to be fixed with three antenna high frequency insulators 2 on antenna body column foot 1.1 one-tenth equilateral triangle of three antenna body column foots.Triangular cone 3 tower bodies are installed on high frequency insulator 2.At triangular cone 3 tops top load cone 4 is installed, the aerial head in top load cone 4 is equipped with lightning protection system and aviation warning lamp simultaneously.Bottom medium wave radiating antenna with between day accent network 5, there is contact tube to be connected.Novel medium wave radiating antenna is by triangular cone 3 and top load cone 4 structure combining.
Main emitter is a triangular cone 3, and the triangular facies basialis pyramidis length of side is 9.716m; End face length of side 0.7m, the bottom surface is to apical side height 105m; Top load cone 4 is the hexagon of falling shape cone, and the bottom surface length of side is a 2m rice, and its cone angle of vertex of a cone face height 1.5m is arrived between 70 °-120 ° in the bottom surface; The tower body total height is 76 meters-110 meters.
The novel wide-band tower medium wave radiating antenna of supporting oneself, the cone angle of its upper end top load cone 4 is 70 °-120 °, and the awl edge lengths is 2 meters, and the center of top load cone 4 is provided with the diverging fixed support, support bracket fastened shape is a beveled structure, is used for stablizing top load cone 4.Top load cone 4 is fixedly mounted on the top of equilateral radiant body triangular cone 3.And be equipped with lightning-protection system and aviation warning lamp.The cone angle of triangular cone 3 is 30 °, and cone base length is 9.716 meters, and the lower end of its upper end and top load cone 4 is fixedly connected, and the lower end of triangular cone 3 is connected with antenna body column foot 1 by insulator 2.Module of aerial is fixed on antenna body insulator 2 and the basis by flange.Triangular cone 3 is interconnected as a wholely in the antenna emitter by angle steel by three hot galvanizing round steel pipe, is fixed on the emitter column foot 1.Top load cone 4 is connected with a day accent network 5 by copper pipe with following triangular cone 3, and antenna master emitter height is 76 meters-110 meters.Triangular cone 3 has the dual-use function that supports medium wave radiating antenna and signal emission.
Operation principle:
1, utilizes the biconical antenna principle, improve the input impedance and the radiation impedance of antenna, reduce reactive component, expand the beamwidth of antenna, the radiation efficiency of antenna is improved;
2, utilize the gradual principle of the conical surface, reduce end reflection and resonance frequency, also do not influence the efficient of antenna;
3, utilize the top load antenna theory, reduce the rate of change of impedance, promote the beamwidth of antenna; Improve input resistance and radiation resistance, reduce impedance rate of change, thereby improved the bandwidth of miniature antenna.
The biconical antenna principle is informed us, and the input impedance of biconical antenna is 2 times of monocone antenna input impedance, thereby has improved the input impedance and the radiation impedance of antenna, reduces reactive component, expands the beamwidth of antenna, and the radiation efficiency of antenna is improved;
The gradual principle of the conical surface is informed us, and antenna is excessive less than 90 ° of directions to conical surface edge from emitter, thereby reduces the reflection in terminal, because cone is bigger, forms certain induction reactance over the ground, has promoted capacitive reactance, and the resonance point of antenna is moved down.
Moreover we also recognize the operating position of other antennas through the support oneself use of the tower medium wave line of departure of broadband, and a common ground of transmitting antenna is that input impedance and radiation impedance are little; Radiation impedance is more little, and the efficient of corresponding antenna just decreases.Therefore we are through detailed demonstration and calculating, according to the experiment of antenna use aspect, we have proposed the mode that adopts bipyramid to combine with top load, the input impedance that improves antenna, reduce the impedance rate of change of antenna, thereby effectively raise the radiation efficiency and the frequency bandwidth of antenna.
For the impedance bandwidth of broadening antenna, add top load cone 4 and make conical taper on main emitter top, effectively improved the resonance length of antenna, make antenna be better than the resonance length of traditional antenna more.Experimental results show that: the utility model is compared with traditional medium wave radiating antenna has the effect of saving soil, high efficiency and high-gain, can be widely used in novelization of medium-wave antenna and the digital medium wave broadcast technology.
