Abstract
The invention provides a strip line feed network for a multi-beam antenna, which works in a C waveband and has simple structure and low cost. A phase shifter is not needed, and four different phase differences (0, 0, -alpha 1, -alpha 1, -2alpha 1, -2 alpha 1), (0, 0, -alpha 2, -alpha 2, -2alpha 2, -2 alpha 2), (0, 0, alpha 2, alpha 2, 2alpha 2, 2alpha 2), and (0, 0, alpha 1, alpha 1, 2alpha 1, 2alpha 1) can be provided for six output ports only by switching, thereby realizing scan of antenna beams.
Description
Technical field
The present invention relates to a kind of method for designing of multi-beam feeding network, particularly a kind of simple in structure, cost is low, the multi-beam feeding network being convenient to realize.
Background technology
Multi-beam antenna is an important technology approach that realizes that wide angle covers, realize that multi-beam then needs between the feeding network output port certain phase difference to be arranged, the general phase difference that needs the use power divider and cooperate phase shifter to meet the demands, such structure more complicated and cost are higher, and the multi-beam feeding network that how project organization is simple, cost is low, be convenient to realize is a research focus.The feeding network of strip lines configuration all has metal ground plate owing to it is two-layer up and down, so do not exist energy to reveal and can not be subjected to basically the interference of external circuit basically.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, cost is low and the strip line multi-beam feeding network that is easy to realize.
The present invention realizes the technical scheme that multi-beam adopts: a kind of one minute six strip line power splitter comprises: merits such as input port 1, output port 2,3,4,5,6,7, switch input terminal 8, output switching terminal 9,10,11,12, one-to-two unequal power distributor 13, one-to-two are divided power divider 14, metal ground plate 15, microwave substrate 16, prepreg 17.Wherein multiple beam forming network is positioned on the surface of a substrate wherein, and another surface is a metal ground plate; The one side of another piece substrate is a metal ground plate, and one side does not have any attachment in addition; Two microwave substrate bond by prepreg.
The present invention does not wait power splitter by using an one-to-two, and seven power splitters such as one-to-two are constructed one fen power splitter of six, and then by output switching terminal switching mutually between port 9,10,11,12, can provide for six output ports (0,0 ,-α
