Abstract

The utility model is about an omnibearing antenna receiving device. The omnibearing antenna receiving device mainly comprises a receiving board, a transmission line, an outer cover, and a pedestal. The receiving board is placed on the pedestal and is covered by the outer cover at the inner side. Metallic receiving bars are printed on the receiving board, and the metallic receiving bars are intentionally aligned in a swastika shape and are forward and backward symmetrical. Spaces are formed between the metallic receiving bars arranged at the front side and the rear side of the receiving board, so that the metallic receiving bars can receive UHF signals from all directions. Wave guiding plates are arranged at the upper and lower end edges of the receiving board, so that a receiving field has an encircled spherical shape, thereby achieving a multi-angle UHF signal receiving capability. The transmission line is used to output the signals to a television or a computer, making the reception of an indoor antenna convenient.

Description

Comprehensive antenna receiving unit

Technical field

The utility model relates to a full-antenna receiving apparatus, which is printed on the receiving sheet? Swastika metallic character modeling and is symmetric around reception conditions, and in the upper and lower end edge of the receiving plate has a guide-wave plate, and can reception field formed around the spherical type, to receive the full range of the UHF signal.

Background technology

Notebook computer, panel TV, computer are popularized gradually in general family at present, and become main flow gradually, and in order to reach better rating quality; And expanding the functional of notebook computer, panel TV, 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, and it is more not attractive in appearance to be positioned at indoor placement, and preferable DTV signal receiving position; Regular meeting changes along with the environmental factor change, for example, and the switch of the putting position of furniture, the putting position of TV, window etc.; Therefore, if desire to obtain best receiving quality, the position and the angle that need constantly the adjustment domestic aerial to put; Very bother constantly, especially many angles can't be swung arbitrarily, make reception have a greatly reduced quality.

The creator specializes in the manufacturing of electronic product to peddle work; Cause is seeing that the cost of traditional product is higher and reception is not good; So be to rely on specialty of itself and working experience for many years; Actively drop into the research reform, add go through test for several times, revise with improvement after, initiate out the utility model finally.

Summary of the invention

The main purpose of the utility model provides a kind of comprehensive antenna receiving unit, to solve existing problem in the above-mentioned prior art.

To achieve the above object, the present utility model relates to a omnidirectional antenna receiving apparatus, which is mainly from the receiver, the transmission line, consisting of cover and base, the rear side of the receiving plate is connected to the transmission line, and so that the receiving plate placed on the base, and the use of the cover lock in the receiving plate inside the front of the receiving plate, the rear end surface of the printed metal receiver, and the metal strip deliberately arranged to receive? swastika-shape and make symmetric around, The receiver front end surface of the metal strip corresponding to produce a spacing, into the central metal received? strip is bent 90 degrees and extends outwardly wider, and in that the receiving plate, the lower end of the wave guide at the edge of a sheet , the receiving pattern of the antenna is spherical.

Further, this guided wave sheet is a upper/lower terminal of being located at dash receiver.

Further, the metal on these dash receiver both ends of the surface receives bar, and the spacing of its corresponding generation is 4mm.

The utility model can reach the UHF signal receiving ability of multi-angle, utilizes transmission line to export signal to TV or computer at last again, obviously than existing antenna progress.

Description of reference numerals: 10-dash receiver; 101,1011, the 1012-metal receives bar; 102-guided wave sheet; The 103-spacing; The 11-transmission line; The 12-enclosing cover; The 13-base.

Embodiment

At first, seeing also shown in Figure 1ly, is the three-dimensional exploded view of the utility model; It mainly is made up of dash receiver 10, transmission line 11, enclosing

cover

12 and 13 of bases, on the front and rear end of this dash receiver 10 is to be printed with metal to receive bar 101, and is provided with guided wave sheet 102 at place, upper and lower end limit; Rear side at dash receiver 10 is connected with transmission line 11 again; At last dash receiver 10 is positioned over base 13, and utilizes enclosing cover 12 that dash receiver 10 is locked in the inboard, and form a domestic aerial (as shown in Figure 2).

Then, see Figure 3, which is a front schematic view of the receiving plate, the receiving plate 10 is printed with a metal bar 101 to receive, and to the metal strip 101 deliberately arranged to receive? Swastika shape and is symmetric around the word (see Figure 4 with shown), located in? swastika-shape extending in the center to the four-terminal side of the metal strip 1011 is received relatively thin, bent 90 degrees to extend outward, and the metal strip to receive wider bold 1012, received via the metal strip 101 The change of the thickness can be controlled in the frequency range between 470-860 MHz, and the receiving plate 10 receives the two metal strip is symmetric, so that the front and back of the metal strip receiving space 103 is formed in 1011 (Figure 5 shown), the spacing distance 103 are the same, and the ideal distance of 4mm, 103 due to the smaller spacing, the frequency range will fall after the reception section, a relatively larger spacing 103, the frequency reception range that falls ? the preceding paragraph, the receiver is not satisfactory, the pitch of the utility model 103 is located in a good impedance matching 4mm, can effectively control the frequency range, and can achieve full capacity to receive UHF signals.

Receiving plate 10 located on the upper and lower end edges of sheet 102 is a wave guide, please continue with the see Figure 5, the guide-wave plate 102 is located at? Swastika-shaped ends of the metal strip edges received, thus allowing reception the field type, such as spherical in general, able to cycle around, but also enhance the ability of UHF signal reception.

Secondly, please continue to consult shown in Figure 6, connect the sketch map of transmission line for the dash receiver of the utility model; The comprehensive reception UHF signal of these dash receiver 10 abilities, and do not receive spatial constraints fully, and can change angle and position arbitrarily; Can both reach desirable reception; A side that is positioned at dash receiver 10 is connected with transmission line 11, can export the UHF signal of all receptions to TV or computer through transmission line 11, makes the UHF signal of all receptions; Can both be complete errorless TV or the computer screen of being presented on, very practical convenient in the use.

In summary, the utility model received through the metal strip printed on the receiver board and extending outward from the central deliberately widen and become? Swastika shape, together with receiver board, the bottom edges of the guide wave plate, expand the scope of the receiver as a spherical receiving pattern, and can reach a full range of UHF signal reception, without space restrictions placed indeed are more progressive than the traditional, practical and reasonable new patent requirements have been met, according to a patent applications.

More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from following accompanying claims and limited and scope; Can make many modifications; Change, or equivalence, but all will fall in the protection range of the utility model.
