Description
Technical field：
The present invention relates to a kind of Gaussian beam production method, belongs to wireless communication field, more particularly to a kind of radiation source
Modulation system, for the excitation two-dimensional Gaussian beam in planar waveguide.
Background technology：
Appearance and photoelectronic development with laser, the research to high bass wave start to be paid attention to by people.Quasi-optics skill
Art is also widely used in the analysis of Gauss wave mode.Gauss wave technology is mainly used in medical research and Experiments of Electromagnetism research
On.The characteristic that its energy concentrates on small range has good application prospect in medical science and experimental study.Present high bass wave

Goal of the invention：In view of the deficiencies of the prior art, the present invention provides one kind can produce dimensional Gaussian in planar waveguide
The method of wave beam, it can accurately design high bass wave beam waist position and waist width.This method power splitter and paster day
Linear array is realized, simple in construction.
Technical scheme：Dimensional Gaussian wave beam production method of the present invention, including power splitter and the paster day such as not
Linear array.Patch antenna array is not by waiting power splitter excitation；Feedback of one radio frequency (RF) coaxial connector sub-miniature A connector as power division network
Incoming interface is connected to the input port of power divider.
Power splitter is not waited to be made up of power distribution part and phase adjusting section.Power divider is by several impedances in parallel
Transformation line is formed so that the power distribution of each output port of power divider is different；Phase adjusting section is propagated by adjusting ripple
Path reaches the effect of phase adjustment.When designing power splitter, we are according on the cross section vertical with the Gaussian beam direction of propagation
Field distribution determine each output port of power splitter amplitude and phase distribution.In the working frequency of high bass wave, beam waist position with
And waist width when determining can design the corresponding power splitter such as not.
The working frequency of paster antenna is determined by metal patch and dielectric thickness and dielectric constant.Paster antenna is using the back of the body
Feed-type encourages, and encourages point position to make paster antenna and power splitter impedance matching by adjusting.
Beneficial effect：1st, the Gaussian beam that two dimension is produced in planar waveguide is realized；2nd, realized in working frequency different
Gaussian beam beam waist position and waist width；3rd, it is simple in construction, advantageously reduce the precision requirement of making.
