Abstract
The utility model relates to a compact polarized compatible omnidirectional miniature antenna, which comprises an antenna unit and an antenna cover, wherein two arms of the antenna unit are formed by bending a flat copper bar or a round copper bar into an M shape and are symmetrically arranged front and back, and are symmetrical left and right; two both side edges of the M shape are perpendicular 90DEG, and the two M-shaped arms of the antenna unit are connected by a feeding port, a balanced unit and an unbalanced unit; The antenna cover is formed by fixing the two antenna unit M-shaped structures and the balanced unit and the unbalanced unit which are positioned at the horizontal section of the two antenna unit M-shaped structures by crystals in an injecting mode, and the feed port is fixedly screwed with a through hole on the antenna cover. The utility model has advantages of very small size and high antenna gain, and is suitable for being installed on vehicles to receive mobile television and digital communication.
Description
Technical field
The utility model relates to a kind of antenna that is used for communication technical field, especially a kind of small-sized polarization-compatible omnidirectional antenna of compactness.
Background technology
At present, with the mobile communication be representative radio communication development rapidly.Along with the raising of requirements such as message capacity, quality, content and the development of integrated circuit technique, the multimedia digital communication mode more and more is subject to people's attention, and moving reception simultaneously becomes one of main communication mode because of its demand that greatly satisfies the user.Thereby more and more higher requirement has been proposed also reception antenna.After for example Digital Television starts broadcasting, bus, all kinds of cars etc. will be one of main users, and this just requires antenna to have characteristics such as high-gain, omnidirectional, low section, small size, installation be reliable and stable.Early stage vertical polarized antenna mostly adopts dipole or monopole (as whip antenna), but the height of this antenna is half-wavelength or quarter-wave, and antenna height is too big, it is low to gain, inconvenience is placed on Move tool, and is also not attractive in appearance, even influences the fail safe of mobile vehicle.On the other hand, be to improve antenna gain in the horizontal direction, the someone adopts the mode of arranging a plurality of oscillators in vertical direction, but complex structure, volume big, difficulty is installed, be not suitable for using under the vehicle-carried mobile situation.Simultaneously, different regional radio waves adopt different polarization modes, generally speaking, must use the antenna of corresponding polarization mode to receive in terminal.
" a kind of analysis of novel circular smart antenna array and the design " on " electric wave science journal " the 2nd phase in 2004, delivered, this article has been introduced to adopt and has been arranged a plurality of oscillators in vertical direction and improve antenna gain in the horizontal direction, realized high-gain although it is so, but increased height, more inconveniently on Move tool, place, not attractive in appearance yet, even influence the fail safe of mobile vehicle.In addition, Chinese patent: " broad-band antenna ", and patent publication No.: 2588561, this patent adopts multiband antenna to improve the antenna broadband, but this antenna bandwidth and little in each frequency band moves in the reception and can not meet the demands fully in Digital Television.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and defective, a kind of polarization-compatible omnidirectional miniature antenna of compactness is provided, comprise antenna element and radome, two arms of antenna element are bent into M shape, forward and backward symmetric arrays with flat copper or circle copper bar, and left and right symmetry, vertical 90 ° of the dual-side of M shape, two M shape antenna element arms link to each other with uneven unit by feed mouth, balance; Radome is to use crystalline, is fixed together the solid through hole on radome of feed mouth spiral shell along two antenna element M shape structures and horizontal segment balance thereof and the injection moulding of uneven unit.
Balance and uneven converting unit can be quarter-wave chokes cover balancer or U type pipe balancer or shunting balancer etc.
The utility model has the advantages that, can transmit and receive horizontal polarization or perpendicular polarization electromagnetic wave, bandwidth, and radiation field is evenly distributed in horizontal plane 360 degree scopes, the part that is parallel to reference planes in two arms of antenna element is when reception or emission level polarized electromagnetic wave, the sense of current in the M type of two antenna arms part on corresponding parallel two limits is identical, the horizontally-polarized electromagnetic wave that receives or launch is strengthened, volume is especially little, the antenna gain height, suitable being installed in the various vehicles, in the taxi dome lamp, be used for received television signal, also can be used for radio communication.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, the utility model comprises antenna element arm 1 and antenna element arm 2, antenna case 5, balance and uneven converting unit 3, feed port 4; Its annexation is: feed port 4 links to each other with two arms 1,2 of uneven converting unit 3 and antenna element by balance, and feed port 4 is passed the through hole on the antenna case 5, and is fixed on the antenna casing 5 by screw thread.
Structurally, the vertical view of antenna element two arms 1,2 is a rectangle frame, and two arms 1,2 of antenna are the center symmetry structurally.The front view of antenna element is a M type structure, left-right symmetric.
Antenna case 5 constitutes the M type by common crystalline.
