For being operated inTE 120WithTE 210The equilateral triangle substrate integration wave-guide resonator of pattern, and conventional metals cavity
In Electric Field Distribution it is identical, electric field change most violent region is respectively positioned on cavity edge and central area, inventive antenna selection
Two right-angled intersection radiating slots are etched in cavity upper surface central area, the table on metal covering has at this moment been cut off due to gap
Surface current, so as to cause the fission of distributed electric field in cavity, forms two kinds of maximum degeneracy resonant modes of electric-field intensity at gap
Formula, thus will produce transverse electric field on gap, electromagnetic energy is radiated.
Technical scheme is described in further detail below in conjunction with the accompanying drawings：
The present invention provides a kind of circular polarisation slot antenna based on triangle substrate integral waveguide resonator, its structure such as Fig. 1 to 3
It is shown.The antenna includes the medium substrate that upper and lower surface is coated with metal level；It is end to end that medium substrate is provided with three rows
Plated-through hole, equilateral triangle substrate integration wave-guide resonator is constituted with dielectric-slab upper and lower surface metal level, dielectric-slab；Medium
The metal level of upper surface of base plate is also provided with two orthogonal rectangular apertures, and two rectangular apertures are located at equilateral triangle substrate
The central area of integrated wave guide resonance chamber upper surface metal level；The lower surface of medium substrate be provided with one be used for feed ground connection
Co-planar waveguide a, corner connection of the coplanar waveguide ground from equilateral triangle substrate integration wave-guide resonator enters equilateral triangle substrate
Integrated wave guide resonance chamber, and the center conduction band of the coplanar waveguide ground and foregoing equilateral triangle substrate integration wave-guide resonator
One jiao of opposite side is vertical；The lower surface of medium substrate is additionally provided with one from medium substrate while the microstrip line extended internally, is somebody's turn to do
The center conduction band of microstrip line and coplanar waveguide ground is connected, and, it is not coated with metal-clad on the medium substrate of the microstrip line both sides.
The antenna of the present invention is by the upper strata metal facet etch two in equilateral triangle substrate integration wave-guide resonator
Length is different and crosses the cross gap of chamber central point, and by positioned at resonator lower metal face and stretching into inside cavity
Coplanar waveguide ground is fed, and is operated in antenna orderPattern andPattern.Wherein, triangle resonator is
Make a call to the end to end plated-through hole array of three rows on the medium substrate of metal by being coated with upper and lower surface and realize.
Antenna measurement for convenience, the lower surface of medium substrate also has one to connect with coplanar waveguide ground central metal conduction band with equal in width
50 ohm microstrips connect.By adjusting the size of resonator and radiating slot, substantially to determine the working frequency range of antenna.True
After the initial value for determining antenna slots length resonant cavity body physical dimension, it can be stretched into by adjusting co-planar waveguide inside resonant cavity
Depth realize the requirement of the impedance matching between driving source and antenna.
In the present invention, plated-through hole diameter is more than 1/2nd of plated-through hole spacing and less than waveguide work wavelength
1/10th, and the thickness of medium substrate will be much smaller than medium wavelength, can just make electromagnetic field in resonant cavity perpendicular to
Do not change substantially on dielectric surface direction, meet after two above condition, energy leakage can be suppressed to and can neglect substantially
Level slightly.Two orthogonal rectangular apertures are as radiating slot, and positioned at the upper strata metal covering central area of antenna, and length is all
It is close with 1/2nd of medium wavelength, antenna is so just can guarantee that in the case of other structures parameter identical, is had more preferably
Radiation efficiency.By optimizing the difference between two gap lengths, the division of two kinds of degenerate modes in cavity can be caused, and cause
The resonant frequency in two gaps is close, is 90 when the line polarization wave of two gap radiations meets constant amplitude and phase difference at some frequencies
During the condition of degree, two radial components are superimposed in far field, just form circular polarisation electromagnetic wave ripple.In addition, antenna is in selection driving source
, it is necessary to select the larger position of mode of operation electric field amplitude needed for cavity during position, so in inventive antenna structure, connecing
Ground co-planar waveguide is located at one angle of cavity, and stretches into the centre position for reaching two gaps on cavity, so can be simultaneously
Take into account both orthogonal degenerate modes.
Cross seam circular polarisation back of the body chamber slot antenna of the present invention is to be encouraged by single feed with 90 degree of phase difference orders
The different gap of two length, so that two kinds of corresponding modes of resonance are produced in cavity, and by gap by electromagnetic energy spoke
Be shot out, when the line polarization wave constant amplitude produced by two gaps and difference be 90 degree when, far field, which is overlapped, just forms entelechy
Change electromagnetic wave.Simultaneously as the triangle substrate integral waveguide resonant cavity that inventive antenna is used, and rectangle or the circular back of the body
Chamber slot antenna is compared, and structure is compacter, convenient layout.In addition, for the linear polarization based on substrate integration wave-guide resonator
Antenna, due to its low section structure and unique working mechanism, causes antenna to can only operate in very narrow frequency range, but right
For two radiating slots can be with the circular polarized antenna of sequential working in different modes, the resonance center frequeH in different gaps
Difference, because when the two gap resonant frequency points are nearer apart, just foring the working frequency range of circular polarized antenna, thus makes
Circular polarized antenna obtains the bandwidth of operation more larger than linear polarized antenna bandwidth.Inventive antenna remains tradition back of the body chamber gap day
The advantage of the preferable radiance of line, while in whole antenna, radiating slot, coplanar wave guide feedback structure resonant cavity make completely
Simple in construction on single-layer medium plate, radiation efficiency is high, substantially reduces processed complex degree, reduces processing cost, also allows flat
Face circuit is integrated to be become to be more prone to.
Embodiments of the invention are realized on the single-layer medium plates of Rogers Duroid 5880 that thickness is 0.5mm,
