The utility model achieves the above object by following proposal.
A kind of Combined television antenna, comprise omnidirectional antenna oscillator and a plurality of directional antenna oscillator, omnidirectional antenna oscillator and directional antenna oscillator are electrically connected to respectively signal processor, omnidirectional antenna oscillator, directional antenna oscillator and signal processor are fixed on the support, and a plurality of directional antenna oscillators arrange centered by the omnidirectional antenna oscillator symmetrically.Omnidirectional antenna oscillator and directional antenna oscillator are connected to same signal processor, can call different antenna oscillators according to different demands, with reach in any case can both clear reception signal purpose.Since the directional antenna oscillator towards range of receiving is had a significant impact, therefore a plurality of directional antenna oscillators are set, can overcome the narrow defective of single directional oscillator range of receiving.A plurality of directional antenna oscillators arrange centered by the omnidirectional antenna oscillator symmetrically, can enlarge most possibly the range of receiving of whole combined antenna, avoid the signal dead angle.
Preferably, described Combined television antenna comprises two directional antenna oscillators.Two directional antenna oscillators arrange substantially along a straight line, and the omnidirectional antenna oscillator is positioned at the centre position of straight line substantially.More preferably, two directional antenna oscillators are identical.Adopt identical directional antenna oscillator, signal processing can be simplified, also can be reduced in the development cost of mould in the manufacturing process, improve scale and benefit.
Preferably, the omnidirectional antenna oscillator is circular, and the directional antenna oscillator is rectangle.The omnidirectional antenna oscillator of circle is placed the center of combined antenna, except reception is more excellent, can also make outward appearance more smooth attractive in appearance, reduce windage when reducing volume.The directional antenna oscillator of rectangle is convenient from the omnidirectional antenna oscillator toward extension, also makes things convenient for the die sinking manufacturing.Above-mentioned shape means that omnidirectional antenna oscillator and directional antenna oscillator are tabular.The tabular antenna oscillator more easily is accommodated among the shell, convenient transportation, the stability in the time of improving work simultaneously.
Preferably, support comprises support central portion and two support extensions that extend round about from the support central portion, and the omnidirectional antenna oscillator is fixed on the support central portion, and two directional antenna oscillators are separately fixed on two support extensions.The shape of support is set according to the shape of antenna oscillator, except reducing as far as possible volume, can also plays better mating reaction, make whole antenna more firm.
More preferably, omnidirectional antenna oscillator and directional antenna oscillator are separately fixed at the up and down both sides of support.Minute both sides arrange antenna oscillator, and oscillator is overlapped in the two side portions of support, can further reduce volume.More preferably, all antenna oscillators arrange in parallel to each other, so can at utmost reduce the thickness of whole combined antenna, conveniently transport, take in and be installed on narrow place.
Preferably, the directional antenna oscillator comprises directed connecting portion and directed radiation section, and directed connecting portion is fixed on the support extension.The radiation function position that permission directional antenna oscillator is set of directed connecting portion is more neatly toward extension.
Preferably, directed connecting portion and directed radiation section form an angle.Take directed connecting portion as datum level, directed radiation section is set obliquely, can adjust whereby on the one hand that signal receives towards, can also reduce front face area on the other hand, thereby reduce the impact of windage.
Preferably, directed connecting portion is provided with reinforcement.The setting of reinforcement can increase the mechanical strength of directed connecting portion, avoids causing because shape is long bending or fractures.
Preferably, also be provided with loam cake and two lower covers of matching with support, loam cake covers support fully, and lower cover is rectangle and partial coverage directional antenna oscillator (particularly directed connecting portion).The profile of loam cake and the profile of support are substantially identical, cover fully and closed supports in reduce as far as possible the space that takies.Lower cover covers the part of directed connecting portion, is convenient to dismounting.
Preferably, also be provided with the supporting seat that is connected with support.Supporting seat is convenient to be installed in antenna body on the surface or parts of any needs.
As television antenna, the receive frequency range of above-mentioned omnidirectional antenna oscillator and directional antenna oscillator is 470 ~ 862MHz, covers whole TV signal uhf band.
The beneficial effects of the utility model are:
(1) omnidirectional antenna oscillator and directional antenna oscillator are used in combination, the signal that can tackle in the multiple situation receives demand;
(2) a plurality of directional antenna oscillators arrange centered by the omnidirectional antenna oscillator symmetrically, enlarge to greatest extent range of receiving, avoid receiving the dead angle;
(3) by adjusting the shape of each oscillator, support and shell, can reduce to greatest extent the space that combined antenna takies, be convenient to take in, transport and install.
