The utility model discloses a frequency band is wide, simple structure to have miniaturization, ability omnidirectional communication function.
Description
Technical Field
The utility model relates to an antenna especially relates to a printing board ultra wide band omnidirectional antenna.
Background
With the development of modern communication technology, more and more wireless electronic devices are provided, and corresponding antennas are required for functions of different frequency bands, so that too many antennas cause a serious electromagnetic compatibility problem. The broadband antenna is beneficial to reducing the number of antennas and improving the electromagnetic compatibility.
Disclosure of Invention
The utility model aims at providing a printed board ultra-wideband omnidirectional antenna, the bandwidth of which is 400 MHz-3000 MHz and can realize omnidirectional communication; while having a smaller size and requiring only one independent mounting location.
The utility model discloses a reach foretell purpose, the technical scheme who takes is:
the utility model provides a printing board ultra wide band omnidirectional antenna, includes the utility model discloses printing board dipole antenna, including antenna house, printing board dipole antenna, installation base.
Wherein, the glass fiber reinforced plastic outer cover is a hollow structure; the printed board dipole antenna comprises a crossed printed board, a rotary lengthened vibrator and a feed structure, the dipole antenna is vertically installed inside the antenna housing, and the dipole antenna is fixed to the installation base through the lower portion of the crossed printed board.
The printed board ultra-wideband omnidirectional antenna is characterized in that: the thickness of the printed board dipole antenna is 0.1-200 m, and the height of the printed board is 500-1500 mm; the diameter of the antenna housing is 25-125 mm, the wall thickness is 1-20 mm, and the groove depth of the antenna housing is 5-15 mm. The diameter of the base is 25-125 mm, and the depth of the groove is 5-25 mm.
The beneficial effects of the utility model
The utility model comprises a printed board ultra-wideband omnidirectional antenna, therefore, the bandwidth is 400 MHz-3000 MHz; because the printed board ultra-wideband omnidirectional antenna can cover the whole ultra-wideband of 400 MHz-3000 MHz, compared with the conventional frequency band antenna biconical antenna, the printed board ultra-wideband omnidirectional antenna realizes full-frequency coverage, and the size is reduced by utilizing the rotary lengthened oscillator, so the printed board ultra-wideband omnidirectional antenna has the characteristic of miniaturization; because the dipole antenna form of the cross printed board is adopted, the structure is simplified, and meanwhile, the dipole form is formed by the cross printed board, so that the omnibearing communication is realized; the printed board ultra-wideband omnidirectional antenna only needs to be installed and fixed at a proper position by utilizing the base and the grooves of the antenna housing, so that the installation steps are simplified.

FIG. 2 is a schematic view of a mounting base and radome grooving
Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the printed board ultra-wideband omnidirectional antenna of the present invention includes an antenna housing 1, a printed board dipole antenna 2, and an installation base 3.
The antenna housing 1 is of a non-metal structure, and a groove line which is inserted and fixed correspondingly to the crossed printed board 21 is formed inside the antenna housing.
The printed-board dipole antenna 2 includes a cross printed board 21, a rotary elongated element 22, and a feed structure 23.
The cross printed board 21 is formed by cross splicing two same printed boards to form a dipole form which is symmetrical up and down; the rotary lengthened vibrator 22 is formed by connecting about 4/1 circular metal rings with the upper metal parts of the crossed dipoles; the center metal of the feed structure 23 is connected to the circular arc intersection of the upper printed board metal portion of the cross printed board 21, and the outer conductor is connected to the lower intersection.
The mounting base 3 is of a metal structure, and a cross printed board 21 is fixed by a slot line of the mounting base.
The printed board ultra-wideband omnidirectional antenna is characterized in that: the thickness of the printed board dipole antenna is 0.1-200 m, and the height of the printed board is 500-1500 mm; the diameter of the antenna housing is 25-125 mm, the wall thickness is 1-20 mm, and the groove depth of the antenna housing is 5-15 mm. The diameter of the base is 25-125 mm, and the depth of the groove is 5-25 mm.
The above embodiment is for the convenience of explanation the utility model discloses the embodiment category the utility model discloses change the cross printing board into three, four etc. and rotatory extension oscillator becomes the combination mode that simple changes such as rectangle, triangle-shaped etc. become to and the frequency extension etc. that adopt this form to go on, all still should contain in above application for patent scope.
