Description
Technical field
The utility model relates to a kind of antenna oscillator, particularly a kind of plate type antenna oscillator.
Background technology
Antenna is a kind of electromagnetic parts that in wireless device, are used for launching or receiving.Engineering systems such as TV, broadcasting, radio communication, remote sensing, every electromagnetic wave that utilizes transmits information, all relies on antenna to carry out work.Along with popularizing of wireless digital TV-set signal, more and more people received television signal out of doors or in moving, and be not confined to indoor.Even at the indoor TV of watching, under a lot of environment, also need antenna be installed on various position.Then have higher requirement to the television antenna of serving as the reception important task this moment: the receive frequency wide coverage, take up room little, can be installed on various environment and can resist various weather, signal reception strong etc.The size of antenna mainly is the influence that receives the antenna oscillator size and dimension.
To 862MHz, existing television antenna uses the scheme of a plurality of oscillator combinations in order to reach the reception of full frequency band to the operation frequency range of DTV mostly between 470MHz, antenna volume is increased and difficult the installation.Most omni-directional antenna then are difficult to guarantee stronger signal reception, do not provide outstanding reception quality in the more weak place of signal.
The utility model content
The purpose of the utility model is the defective that overcomes above-mentioned antenna, provides a kind of simple in structure, is convenient to manufacture, and received signal quality is high, and signal cover is wide, the plate type antenna oscillator of being convenient to install.
The utility model achieves the above object through following scheme.
A kind of plate type antenna oscillator, said plate type antenna oscillator is a rectangular metal sheet, is provided with in the rectangular metal sheet to be divided into the linear opening that the multistage width differs, power feed hole is arranged on linear opening both sides.
The output impedance of said plate type antenna oscillator is about 75 Ω; To adapt to the coaxial cable that is connected on the power feed hole; The impedance of coupling cable reduces the reflection loss effect in the signal conveys process, and said impedance can realize through the shape and the size of regulating linear opening.
Linear opening is divided into multistage, and adjacent two sections width is different.In preferred scheme, said linear opening comprises leading portion, stage casing and back segment, and leading portion is connected through the stage casing with back segment.More preferably, the width of leading portion and back segment equates and greater than the width in stage casing, forms the linear opening of the wide intermediate narrower in two ends.More preferably, the length of back segment and leading portion is than being 4:1 ~ 6:1, and the length of stage casing and leading portion is than being 7:1 ~ 9:1.
In preferred scheme, rectangular metal sheet is the rectangle sheet metal, and linear opening is positioned on the perpendicular bisector of rectangle sheet metal minor face.Rectangular metal sheet is done rectangularity, be convenient to antenna and be installed in long and narrow place, minimizing takes up room.
Preferably, when rectangular metal sheet was the rectangle sheet metal, the length of linear opening was 2/5 ~ 3/5 of rectangle metal length of a film edge lengths, and the Breadth Maximum of linear opening is 1/5 ~ 1/7 of a rectangle sheet metal bond length.
Preferably, said rectangular metal sheet is provided with a plurality of location holes, and a plurality of location holes are that axial symmetry is distributed on the rectangular metal sheet with linear opening.The location hole number is many more, and fixing of rectangular metal sheet is firm more; Symmetrical distribution can make fixing used power be uniformly distributed on each location hole.
Preferably, four angles of rectangular metal sheet are provided with chamfering, and at least one group of opposite side of rectangular metal sheet is provided with groove.Chamfer design makes said antenna oscillator have better signal reception, and is more suitable in being installed in the antenna box body with chamfering, preferred circular arc chamfering of chamfering or straight chamfering; And groove design is convenient to oscillator is fixed on the antenna box body.
Preferably, the long edge lengths of rectangle sheet metal is 380 ± 20mm, and bond length is 215 ± 20mm.The thickness of said rectangular metal sheet is 0.5 ± 0.2mm.
The range of receiving of said plate type antenna oscillator covers whole TV signal uhf band 470 ~ 862MHz, and signal receiving quality is high.
Compared with prior art, the utlity model has following beneficial effect:
The said plate type antenna oscillator of the utility model, simple in structure, to be convenient to manufacture, received signal quality is high, and signal cover is wide, and is easy for installation and take up room little.
