Abstract

The utility model discloses a directivity annular indoor antenna, in particular to an antenna which receives signals at a half-power angle, can receive UHF and VHF high-frequency signals, and can filter the interference from the reception and transmission of signals via a 4G mobile phone. The antenna mainly comprises a receiving board, a coaxial cable, an outer cover and a base, wherein the receiving board is arranged in the base and is coated on the inner side through the outer cover, a wave guiding plate is arranged on the top end of the receiving board, then a trapezoid plate, a concave plate and a reflecting plate are formed downwards from the wave guiding plate at intervals, so that a receiving field has an encircled spherical shape, thereby achieving an omnidirectional UHF signal receiving capability. The wave guiding plate not only can carry out effective filtering, can prevent the high-frequency interference, and can receive the VHF high-frequency signals at the same time; moreover, the reflecting plate with an arc-shaped bottom part has excellent gain effect, and can strengthen the signal reception.

Description

Directive property doughnut internal antenna

Technical field

The utility model relates to a kind of directive property doughnut internal antenna, to be provided with the guided wave sheet in the top of dash receiver, and downwards spacing forms trapezoidal, spill sheet and reflector plate, by being spaced of several sheet metals, makes dash receiver can receive the high-frequency signal of UHF and VHF.

Background technology

Present notebook computer; panel TV; computer is popularized gradually in general family; and gradually become main flow; and in order to reach better rating quality; and expansion notebook computer; panel TV functional; many people are the external domestic aerial of meeting usually; but general domestic aerial is generally a planar design and is hung on metope; not only volume takes up space greatly; it is more not attractive in appearance to be positioned at indoor placement, and better digital television signal receiving position, often can change along with the environmental factor change; for example; the putting position of furniture; the putting position of TV; the switch of window etc., therefore, if want to obtain best receiving quality; need constantly to adjust position and the angle that domestic aerial is put; very trouble inconvenience, especially many angles can't swing arbitrarily, so that reception is had a greatly reduced quality.

The inventor specializes in the manufacturing of electronic product to peddle work, because of higher in view of the cost of traditional product and reception is not good, so be to rely on the specialty of itself and working experience for many years, actively input research reform, after adding test, correction and the improvement of going through several, initiate out the utility model finally.

Summary of the invention

The purpose of this utility model is to improve defective of the prior art, a kind of good looking appearance is provided, receives the strong domestic aerial of signal capabilities.

For reaching above-mentioned purpose, the utility model proposes a kind of directive property doughnut internal antenna, refer to that especially a kind of half-power angle receives signal, and can receive the high-frequency signal of UHF and VHF, can filter the interference that 4G cell phone received and transmitted signal.It mainly is by dash receiver, coaxial cable, enclosing cover and base form, this dash receiver is discoideus, and be arranged in the base, and can utilize enclosing cover that dash receiver is coated on the inboard, the top that is positioned at dash receiver is a guided wave sheet, and the interference of high frequency is avoided in effectively filtering, form symmetrical trapezoidal in the downward spacing of guided wave sheet again, and mutually form a gap, and can receive the frequency range of UHF, be positioned at trapezoidal below to form the spill sheet, this spill sheet and trapezoidal maintain a gap, and can receive the high-frequency signal of VHF, as for the reflector plate of bottom, receiving angle is kept between 100 degree-180 degree, and the effect of tool gain, to strengthen the reception of signal.

The beneficial effects of the utility model are, design by the sheet metal of dash receiver, make reception field pattern such as same spherical around, reach the signal of comprehensive reception UHF, can not only prevent High-frequency Interference, and the splendid gain effect of tool, and can export signal to TV or computer by coaxial cable, compare with existing traditional antenna and have significant progress.

Embodiment

At first, see also shown in Figure 1, be three-dimensional exploded view of the present utility model, it is mainly by dash receiver 10, coaxial cable 11, enclosing cover 12 and base 13 form, this dash receiver 10 is discoideus, the upper surface is provided with guided wave sheet 101, trapezoidal 102, spill sheet 103 and reflector plate 104, and be provided with output 100 in centre, the joint 110 of the coaxial cable 11 of itself and base 13 joins, can export the signal that receives to TV by coaxial cable 11, computer or mobile phone, dash receiver 10 then is arranged at base 13, and enclosing cover 12 is combined with base 13 clips, and forms a domestic aerial 1 (as shown in Figure 2).

Then, see also shown in Figure 3ly, be the front schematic view of dash receiver, this dash receiver 10 is positioned at the top to be provided with guided wave sheet 101 for discoideus and be provided with several sheet metals, and it forms anchor ring according to the outward appearance of dash receiver 10, and effectively the interference of high frequency is avoided in filtering simultaneously; Be arranged at intervals with corresponding trapezoidal 102 downwards as for guided wave sheet 101, this trapezoidal 102 for scalariform is arcuation in the end limit, and deliberately leaves gap 105 in trapezoidal 102 of correspondence, so that the frequency range of comprehensive reception UHF; Spill sheet 103 then is formed at trapezoidal 102 belows and forms a groove shape, shortens circular arc in outer shroud in then, and this spill sheet 103 has slit 106 equally with trapezoidal 102, can by the groove arrangement of spill sheet 103, receive the high-frequency signal of VHF; The bottom that is positioned at dash receiver 10 then is a reflector plate 104, and it is semiarc shape, and forms a gap 107 with the spill sheet 103 of top, makes reflector plate 104 can reach the multi-angle remission of about 100-180 degree, and the reception of enhancing signal reaches splendid gain effect.

During use, please continue to consult shown in Figure 4, schematic diagram for the utility model use, the high-frequency signal of this domestic aerial 1 comprehensive reception UHF signal of energy and reception VHF, and be not subjected to spatial limitation fully, and can change arbitrarily angle and position, can both reach desirable reception, and can be by with coaxial cable 11 and computer 2, TV 3 or mobile phone 4 connect, and make the signal mat of reception transfer to computer 2, TV 3 or mobile phone 4 can be with the signals that receives, know and fast transmission, for user's program of feeling at ease to watch, needn't worry the puzzlement of disconnected news, very practical convenient in the use.
