Abstract
The present invention relates to a kind of multi-notch wideband omnidirectional antenna that encircles loading, comprise radiation fin (1), parasitic radiation paster (2), following radiation fin (3), dielectric substrate (4), floor (5), mounting plate (6), main feeder (7), radome (8), distributing point (9) is equipped with loaded ring (17) on last radiation fin (1) and parasitic radiation paster (2).Described loaded ring (17) is arranged on the end of vertically going up the regular shape before radiation fin (1) and parasitic radiation paster (2) gradual change begin.The loaded ring antenna makes the inhomogeneities of azimuth plane directional diagram obtain favourable improvement, on the directional diagram symmetry of vertical plane, improvement is arranged, loaded ring and primary antenna radiant body is connected on the other hand, concerning primary antenna, be equivalent to a last ring in parallel, changed the matching performance that original impedance has improved antenna, and made antenna structure firmer firm.
Description
Technical field
The present invention relates to a kind of antenna, be specifically related to a kind of multi-notch wideband omnidirectional antenna that encircles loading.Be used for mobile communication system as indoor covering and outdoor cell embellished antenna low, medium gain.
Background technology
At present some notch wideband omnidirectional antenna all exists in the defective of the directional diagram symmetry difference of the inhomogeneities of azimuth plane directional diagram and vertical plane, announced a kind of quaternary recess antenna 200810156045.2, comprise radiation fin 1, parasitic radiation paster 2, following radiation fin 3, dielectric substrate 4, ground 5 plates, mounting plate 6, main feeder 7, antenna 8 covers, distributing point 9, coaxial feeder 12, this " a kind of quaternary recess antenna " also exist in the defective of the directional diagram symmetry difference of the inhomogeneities of azimuth plane directional diagram and vertical plane.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of higher gain that obtains is provided, working band is wide, and level distribution is even, improves the small and exquisite simple quaternary recess antenna of communication quality.
The present invention includes radiation fin 1, parasitic radiation paster 2, following radiation fin 3, dielectric substrate 4, floor 5, mounting plate 6, main feeder 7, antenna 8 covers, distributing point 9, last radiation fin 1 and following radiation fin 3 quadratures have parasitic radiation paster 2, and end before distributing point 9; Slit in the middle of radiation fin 1 and the following radiation fin 3 is the line of rabbet joint, be affixed on jointly on the dielectric substrate 4, following radiation fin 3 links together with metal quality plate 5, place a plastic mounting fixed head 6 below the floor 5, mounting plate 6 inserts in the radome 8, it is characterized in that: on last radiation fin 1 and parasitic radiation paster 2 loaded ring 17 is installed.Described loaded ring 17 is arranged on the end of vertically going up the regular shape before radiation fin 1 and 2 gradual changes of parasitic radiation paster begin.Described loaded ring 17 can adopt annulus, Fang Huan, the capable annular of plum blossom lobe, and the size of plum blossom lobe, sinking degree can be different.
Loaded ring antenna of the present invention makes the inhomogeneities of azimuth plane directional diagram obtain favourable improvement, on the directional diagram symmetry of vertical plane, improvement is arranged, loaded ring and primary antenna radiant body is connected on the other hand, concerning primary antenna, be equivalent to a last ring in parallel, changed the matching performance that original impedance has improved antenna, and made antenna structure firmer firm.

Embodiment
Below with reference to drawings and Examples technical scheme of the present invention is described in detail.
As Fig. 1, wherein 1 is last radiation fin, and 3 are following radiation fin, and 4 is dielectric substrate, and 5 is the floor, and 6 is mounting plate, and 7 is main feeder, and 8 is radome, and 9 is distributing point, and 12 is coaxial feeder, and 17 is loaded ring.
As Fig. 2, wherein 2 are the parasitic radiation paster.
Last radiation fin 1 and following radiation fin 3 quadratures have parasitic radiation paster 2, and end before distributing point 9.On last radiation fin 1 and parasitic radiation paster 2, loaded ring 17 is installed, slit in the middle of last radiation fin 1 and the following radiation fin 3 is the line of rabbet joint, be affixed on jointly on the dielectric substrate 4 and fixed, following radiation fin 3 is a ground connection, and for making down radiation fin 3 ground connection reliably, its bottom curves the right angle, so that link together with metal quality plate 5, for easy for installation, the floor 5 following plastic mounting fixed heads 6 of placing, mounting plate 6 inserts in the radomes 8.Loaded ring 17 is arranged on the end of vertically going up the regular shape before radiation fin 1 and 2 gradual changes of parasitic radiation paster begin.Loaded ring 17 is as a ring, and it can adopt shapes such as annulus, Fang Huan, the capable ring of plum blossom lobe, and the size of plum blossom lobe, sinking degree can be different,
Though the present invention with preferred embodiment openly as above; but they are not to be used for limiting the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the invention; from when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection range of protection scope of the present invention.
