The features such as, therefore be widely used in microwave integrated circuit, antenna and aerial array.Its radiator is printed on the one of dielectric-slab
Side, other side type metal floor, such antenna structure is simple, easy to process, but its bandwidth of operation is very narrow, and performance is situated between
Matter substrate is affected, and communication system dual-use at present requires that the work belt of antenna is wide.Obviously, narrowband
Microstrip antenna is not well positioned to meet such performance requirement.In general, using microstrip line or coaxially to aerial radiation patch into
Row feed motivates electromagnetic field between conductor patch and earth plate, and passes through the outside spoke in gap between patch surrounding and ground
It penetrates.But such feeding classification can not broaden the bandwidth of operation of antenna well.By opening diesis slot on patch, load is posted
Raw minor matters realize antenna radiation impedance matching with the mode for increasing the transformation antenna structure such as air layer to reach broadening bandwidth
Purpose is, it can be achieved that impedance bandwidth 20%~70% differs.It also can be very good to increase antenna by using the mode of couple feed
Bandwidth, achieve the effect that increase antenna impedance bandwidth.

Reason, which can probably be divided into, to be increased parasitic element, reduce the built-in quality factor of antenna and improves degree of coupling three classes method.In addition
The different feeding classification of microstrip antenna also has a great impact to circular polarisation, and microstrip antenna realizes that the feeding classification of circular polarisation is main
It is divided into (1) single-point feedback, is mainly based upon Cavity theory, generates two radiation cross polarizations using perturbation excitation and realize entelechy
Change, but the axial ratio bandwidth that such feeding classification is able to achieve is very narrow, and the performance requirement of not applicable wide axis ratio.(2) n-point feed,
It is fed using multiple feed points, feed point is presented with the excitation of out of phase, to realize the job requirement of circular polarisation.This way compared with
The performance of circular polarisation easy to accomplish, and axial ratio bandwidth is wider, only generally requires and is increasing additional power splitter and phase shifter
The feeding network of composition, therefore increase in cost of manufacture.Relatively common is two point feed and 4 points of feedbacks using sequence spiral
Electricity.(3) multivariate method, this mode are realized by adjusting position between unit and phase using multiple linearly polarized radiations member
Circular polarisation, it is similar with n-point feed method.For multivariate method compared with n-point feed, feeding network is relatively simple, but structure is more multiple
It is miscellaneous, it is at high cost.
In conclusion problem of the existing technology is:
(1) single-point feedback is motivated using perturbation generates two radiation cross polarizations realization circular polarisation, but feed side in this way
The axial ratio bandwidth that formula is able to achieve is very narrow, and the performance requirement of not applicable wide axis ratio.
(2) n-point feed is fed using multiple feed points, and feed point is presented with the excitation of out of phase, to realize circular polarisation
Job requirement.This way is easier to realize the performance of circular polarisation, and axial ratio bandwidth is wider, only generally requires and is increasing
The feeding network of additional power splitter and phase shifter composition, increases in cost of manufacture.Relatively common is two point feed and use
The four-point feed of sequence spiral.
(3) multivariate method is using multiple linearly polarized radiations member, realizes entelechy by adjusting position between unit and phase
Change, it is similar with n-point feed method.For multivariate method compared with n-point feed, feeding network is relatively simple, but structure is increasingly complex, at
This height.
