Abstract
Oblique beam antenna in Ku frequency range includes multiple components: feeding network, work division network, and phase change etc. The antenna is singleline polarized oblique beam antenna with flatwise type antenna body.
Description
Technical field
The invention of this antenna is the top set formula Ku frequency range satellite television receiving antenna of the train that is fit to have limitation in height, automobile, steamer.
Background technology
The satellite earth antenna that uses all is with parabolic antenna or normal direction plate aerial receiving satellite signal at present, adopt waveguide crack KU frequency range plate aerial too according to the disclosed plate aerial of patent No. CN1494751A, but what it adopted is that a kind of equally distributed axle is to becoming structure, the directional diagram that it produced is consistent with normal direction, and antenna need erect and just can use.Use just very inconvenient to car, ship like this, because the road limit for height is brought inconvenience during high vehicle speeds, for solving the Ku band oblique wave beam antenna of this practical problem antenna pattern off-normal of the present invention direction, make it can level be installed on the roof and can watch satellite television programming.
Summary of the invention
The present invention is a kind of Ku band oblique wave beam antenna, adopts non-ferrous metal aluminium, copper through cut or use plastic processing to become to carry out water metal cladding technology behind the mould and realize moulding.Its original creation part is:
A, by calculating the transmission of guide wavelength along the waveguide line of rabbet joint (9 among Fig. 3), the difference that changes the branch road transmission path that power splitter (Fig. 3) tells changes the stack of freedom of the air electromagnetic field and makes its main lobe direction off-normal direction θ
N
B, reach a kind of slit (5 among Fig. 2) excitation feed method by lower floor's feed waveguide (Fig. 1) mode and make its synthetic wave beam off-normal direction θ
k, when feeding network and radiation front are integrated, produce main lobe off-normal orientation angle θ=θ
n+ θ
k
As shown in Figure 1, cavity type (6 among Fig. 2) the waveguide slit formation antenna that upper, middle and lower-ranking is screwed the back formation slant beam that is integrated realizes that above-mentioned satellite-signal receives purpose.Distribute to each branch road by waveguide slot (9 among Fig. 3) through ladder coupling (8 among Fig. 3) and give feed waveguide (4 among Fig. 2), be radiated and finish specification requirement in the air by slit (among Fig. 2 5) at last via translation interface (3 among Fig. 1).
The present invention can be installed on automobile or the steamer easily, makes these be subjected to the delivery vehicle of physical height restriction can receive satellite-signal freely.
