Description
Technical field
The invention belongs to antenna technical fields, and in particular to a kind of circularly polarization microstrip patch antenna.
Background technique
Circular polarized antenna emits as a kind of or receives the component of radio wave, play in a wireless communication system to
Important role is closed, especially in satellite communication and Spacecraft TT&C equipment.
Present satellites navigation equipment is answered in fields such as positioning, measurement, time service, high-precision agricultural and intelligent transportation
With increasingly extensive.Navigation equipment is generally dynamically poor in real time using RTK(in order to obtain the above high accuracy positioning requirement of decimeter grade
Point-score) technology, the antenna of equipment will generally have dual frequency characteristics at this time, and should have wider bandwidth of operation (gain bandwidth, wave
Band is wide and axial ratio bandwidth) and size more compact, simultaneous processing manufacture will be simple etc..Since micro-strip paster antenna has shape
Shape is small, at low cost, easy conformal, easy processing and the advantages that circular polarisation easy to accomplish, and is widely used, and circular polarized antenna is also such as
This.
The problem of current circular polarized antenna is primarily present are as follows:
1. common microstrip antenna whole realization single-layer medium realizes a working band, this bandwidth of operation is narrow, work
Bandwidth only has 5%z or so, cannot apply very well in ultra wide band (spread spectrum) communication system.If increasing bandwidth, generally require to adopt
Use the medium of low-k as antenna substrate material, antenna size will increase at this time.
2. conventional helical antenna bandwidth, wave beam is wide, directional diagram is symmetrical, wide angle circular polarisation performance is good, the disadvantage is that can only be real
An existing polarization mode.In the occasion for needing double-circle polarization, it is unable to satisfy application.
3. array antenna (or a period of time deformation), symmetrical, the wide angle circular polarisation performance of bandwidth, directional diagram is good, the disadvantage is that wave beam
It is not wide enough, structure is more complex, size is larger.
Traditional microstrip antenna whole realization double frequency is using stacked, i.e. one working band of general one layer of realization, and two layers
Superposition is to realize double frequency.The radiation of its whole realization upper frequency at the middle and upper levels, lower layer realize the radiation of lower frequency.Wherein lower layer
Radiation patch serve as the floor of last time patch.This structure feed is more complicated, at the same the patch on upper layer often under the influence of
The performance of layer patch, causes the decline of lower layer's patch performance, also, conventional microstrip Antenna Operation narrow bandwidth, cannot cover very well
Multiple satellite navigation systems.If increasing bandwidth, medium using low-k is generally required as antenna substrate material, this
When antenna size will increase.
Circular polarized antenna is since there is no polarization mismatch phenomenon, it is easier to obtain the lower balance reception power of correlation and
Greater advantage is presented.A pair of of left-hand circular polarization wave and the cross polarization each other of right-handed circular polarization wave, it is ideally a pair of to hand over each other
It pitches polarized wave to be mutually isolated, i.e., is the signal that can not receive RHCP incoming wave with the antenna of LHCP, vice versa.In fact
Not absolute circular polarisation and linear polarization, the endpoint trace of the instantaneous electric field vector of any polarized wave are one oval, elliptical length
The ratio between axis and short axle are referred to as axis ratio AR (Axial Ratio), are generally indicated with dB.Axis ratio is that one of circular polarized antenna is important
Performance indicator, it represents the purity of circular polarisation, generally the bandwidth by axis than being not more than 3dB, is defined as the circular polarisation band of antenna
It is wide.It is to measure antenna to the important indicator of the signal gain otherness of different directions.
The characteristics of circularly polarised wave is, the vertical component of electric field and the equal in magnitude of horizontal component and 90 degree of phase phase difference.One
As in the case of, microstrip antenna is linear polarization.But if special feeding classification is used to microstrip antenna, two are motivated in patch
Degeneracy obtains orthogonal modes, is allowed to amplitude equal phase and differs 90 degree, it can obtains circularly polarised wave.Circular polarisation is rotated according to electric field
Direction is different can be divided into left-handed and right-handed circular polarization again.Circularly polarized signal can change by reflection, strong according to reflection signal
Weak, whether we substantially can be inferred that the signal by reflection and order of reflection, and in this, as the foundation of signal detection,
So in measurement and control area application also than wide.
Circular polarized antenna usually has the forms such as helical antenna, right-angled intersection a period of time, microstrip antenna, wherein due to spiral day
Line is the disadvantage is that a polarization mode can only be realized.It is higher to intersect a period of time this kind of antenna profile, is unfavorable for being integrated into mobile terminal and sets
For, microstrip antenna is with its distinctive advantage, such as profile is low, light weight and cost is small, easily conformal, and is easy to be formed simultaneously
Left-handed and two kinds of polarized signals of dextrorotation become essential in special occasions.But traditional microstrip antenna bandwidth of operation is narrow, and one
As be 3%-5%, in spread spectrum communication, be not available.Broadening circular polarized antenna frequency bandwidth is the key that improve its practical value,
It is especially applied in ultra-wideband communications, interference free performance can be greatly improved, be the research for realizing antenna broadband and miniaturization
Emphasis.
