Description
Technical field
The utility model relates to antenna technical field, more particularly to a kind of ultrashort wave antenna.
Background technology
The major technique starting point of existing ultrashort wave antenna is the size of antenna and the matching performance of antenna, various technologies
Using carrying out all around this 2 points, very marvelous achievement is also achieved.Wherein, reduce what antenna size mainly used
It is antenna fulcrum short circuit technology, i.e., the most weak point of current amplitude is found on antenna, and this point and floor is short-circuit；Improve day
The matching performance of line mainly uses port match network loading technique, is adjusted by impedance of the matching network to antenna port
Make its matching.
But the performance boost of communication apparatus demand in face of gradually being lifted, only size and matching etc. is far from
No more.In new communication link model, have to the horizontal plane gain requirement of antenna and be obviously improved, index is by original big
In -8dBi liftings to -4dBi is more than, in face of new use demand, we have devised the antenna form in this patent, Neng Gouming
Aobvious lifting antenna gain, the matching performance of antenna are also splendid.
The content of the invention
The shortcomings that in order to overcome the above-mentioned prior art, the purpose of this utility model are to provide a kind of simple in structure, raising day
The ultrashort wave antenna of the horizontal direction gain of line.
To reach above-mentioned purpose, the utility model uses following technical scheme, a kind of ultrashort wave antenna, including antenna sheet
Body, is fixedly connected on the metal dish of antenna body upper end, is fixedly connected on the metal floor of antenna body lower end；The metal
Floor is equipped with radio-frequency joint, and the radio-frequency joint is fixedly connected on metal floor by flange, further includes matching network and connects
Mouthful, which fixes and is located on antenna body.
The shape of the antenna body is up-small and down-big knife horse type.
The metal dish includes oval disc, is located at the rectangular channel of oval disc bottom, and in the rectangular channel
The central coaxial of the heart and oval disc, mounting hole, the upper end peace of the antenna body are uniformly provided with the rectangular channel
In rectangular channel and the screw by being through in mounting hole is fixedly connected with metal dish.
The antenna body be made of by the printed board of high 300mm, printed board dielectric constant 2.2, thickness 1.5mm,
Printed board top width 124mm, bottom width 220mm, the metal covering of printed board is monopole.
The metal floor aluminum workpiece, the flange that 15mm high is designed with workpiece are used for and antenna body carries out
It is fixed.
The radio-frequency joint is N-K connectors.
The beneficial effects of the utility model are：Simple in structure, small, light-weight, high gain, is loaded oval by top
Shape metal dish improves gain, the height without increasing antenna；By loading matching network in output port with broadening antenna standing wave
Bandwidth, and network degradation very little.
