Summary of the invention
The utility model discloses the small-sized panel TV directional antenna of a kind of broadband high-gain according to the deficiencies in the prior art.Problem to be solved in the utility model provides a kind of shortcoming that overcomes conventional television antenna, satisfies the small-sized panel TV antenna that system such as mobile TV covers needs, broadband high-gain.
The utility model is achieved through the following technical solutions:
The small-sized panel TV antenna of broadband high-gain is characterized in that:
The radiation patch that comprises base plate, arranges by insulation column and base plate secured in parallel; Fixedly there is coaxial connector at the base plate middle part, and the center conductor of coaxial connector extends the probe to the radiation patch feed.
Further described radiation patch plane is " E " shape.
Described probe is staight needle, welds with " E " shape radiation patch.
Or described probe is " L " shape probe, does not contact near " E " shape radiation patch feed that is coupled.
Above-mentioned base plate is the notch plate that there is bent angle on flat board or dual-side edge.
The utility model helpfulness, the utility model antenna frequency band can reach 600～820MHz, and gain can reach 9dBi, and size can be little of 250mm * 250*55mm, realized broadband, high-gain, small size.The utility model satisfies the needs that system such as mobile TV covers fully.

Embodiment
Further describe below by the utility model of embodiment; present embodiment only is used for the utility model is further detailed; but can not be interpreted as the restriction to the utility model protection range, those skilled in the art can make the scope that some nonessential improvement and adjustment belong to the utility model protection according to above-mentioned content of the present utility model.
In conjunction with Fig. 1 to Fig. 4.
The small-sized panel TV antenna of broadband high-gain, the radiation patch 1 that comprises base plate 2, arranges by insulation column 5 and base plate 2 secured in parallel; Fixedly there is coaxial connector 3 at base plate 2 middle parts, and the center conductor of coaxial connector 3 extends the probe 4 to radiation patch 1 feed.
Preferred radiation patch 1 plane of this example is " E " shape.
Probe 4 tops are staight needles, and are vertical with " E " shape radiation patch 1, and probe is welded direct on " E " shape radiation patch.Another kind of probe 4 top structures are " L " shapes, and " L " shape latter end is parallel with " E " shape radiation patch 1, and " L " shape latter end is close but do not contact " E " shape radiation patch 1.
Base plate 2 is notch plates that there is bent angle on flat board or dual-side edge.
Fig. 1 is the utility model antenna perspective view.As shown in the figure, the base plate of this routine antenna 2 be arranged in parallel with radiation patch 1, the re-entrant angle limit 2a of the oriented radiation patch 1 one end bendings in base plate 2 both sides, in fact also can adopt no re-entrant angle limit 2a surface plate; Base plate 2 fixedly be arranged in parallel by insulation column 5 with radiation patch 1, can also install insulation column 5 to strengthen antenna at the center equipotential according to requirement of strength at four jiaos of insulation columns 5 that equal height is set; At base plate 2 middle parts connector 3 is arranged, connector 3 is coaxial cables of coaxial connector or terminal band coaxial connector, the center conductor of coaxial connector is connected with feed probes 4, feed probes 4 distributing point corresponding with radiation patch 1 middle part connects, this example adopts " E " shape radiation patch 1, feed probes 4 is corresponding with pin leading section in " E " shape radiation patch 1, and the distributing point of radiation patch 1 is positioned at the front end of " E " shape radiation patch horizontal median axis.
Fig. 2 is the plane graph that " E " shape radiation patch 1 one side is arranged.As shown in the figure, radiation patch 1 projection drops in base plate 2 planes, and feed probes 4 is arranged on pin leading section in " E " shape radiation patch 1.
In conjunction with Fig. 1 and Fig. 2, this example " E " shape radiation patch 1 is made by sheet metal, so-called " E " shape is to have two rectangular channels in rectangle plane, two rectangular channels form two openings of radiation patch 1 one sides, two rectangular channels be arranged in parallel and are parallel on one side with radiation patch 1 simultaneously, and above-mentioned feature is " E " shape in conjunction with constituting radiation patch 1 planar profile integral body.
Fig. 3 is the utility model antenna left side TV structure schematic diagram, is expression connector 3 and feed probes 4 convenience, and Fig. 3 looks on a left side part and do not express dull and stereotyped re-entrant angle limit 2a; Fig. 4 is the utility model Fig. 2 BB cross section structure schematic diagram.As shown in the figure, base plate 2 be arranged in parallel with radiation patch 1, and insulation column 5 constitutes the support of parallel construction; Among Fig. 3, base plate 2 outsides are connectors 3, and the center conductor of coaxial connector extends feed probes 4; Specifically do not express staight needle formula feed probes or " L " shape feed probes among the figure, staight needle formula feed probes or " L " shape feed probes all are existing probe structures commonly used, staight needle formula feed probes 4 welds together with E shape radiation patch, and " L " shape feed probes does not contact the feed that is coupled near " E " shape radiation patch.
