One of select.Phased array can provide the beam switchover of low time delay in the case of gain stabilization, realize accurate scanning direction, be
Specific intensive place provides communication and ensures.However its expensive cost, the complexity that hardware is implemented, heat dissipation and structure space have
Limit becomes the main problem for restricting its development.In contrast, multibeam antenna also has millimeter in satellite communication and car radar
Wave application, and with minimizing, advantage at low cost can be applied to Miniature Terminal equipment.
That realizes multi-beam function mainly has the technologies such as Butler matrixes, Blass matrixes, Rotman lens.Wherein Blass
Matrix amplitude can be controlled freely, and the wave beam number formed is more, and input port isolation is good, should actually use flexibility
Height, but it is dissipative network and complicated.Most by the network number of beams of Rotman lens forming, sidelobe level is low,
Bandwidth is high, but oversized, therefore is not suitable for mini-plant.
Butler matrixes are a kind of multiple-port cells, and the electromagnetic wave of out of phase can be formed to different port input, and then
Multiple electromagnetic waves of phase equal difference variation are formed in output terminal, then the wave beam of specific direction is synthesized by oscillator space.And it hands over
Device is pitched as Butler matrix building blocks, to form the necessary component of out of phase electromagnetic wave.
Conventional interleaver depends on microstrip line or metal waveguide structure more.Microstrip line construction is simple, small, however in milli
Meter wave frequency band dispersion is serious, and loss is beaten, therefore constrain its application in millimeter wave；Although metal waveguide loss is low, in milli
For VHF band since wavelength is short, the requirement to metal contact is extremely stringent.To avoid gap leaky wave problem, so as to cause whole steady
Qualitative difference.
