Description
Technical field
The utility model is related to radio frequency arts, and in particular to a kind of transition knot of novel millimeter waveguide to micro-strip
Structure.
Background technology
Growing with microwave-radio technology, the rf frequency of people's application is higher and higher, is wanted to the index of product
It asks more and more precise and tiny.Since millimeter wave frequency band wave band is short, spatial resolution is high, can produce small, light weight, anti-interference
Ability is strong, differentiates the high various product of resolution, more and more common in the application of RF application.
But mm wave RF signal is lost bigger than normal in circuit, and especially transition is poor at switching, carries out rectangular waveguide
Good transition to microstrip line construction seems and is even more important.Traditional Millimeter Wave Rectangular Wave-guide is generally adopted to the transition of microstrip line
With " rectangular waveguide-ripple pearl probe-microstrip line " structure.The traditional structure transition is primarily present three major issues：
1）Structural sensitivity is high, and the processing request and matching requirements to ripple pearl probe are high, it is difficult to control；
2）Coupling bandwidth is relatively narrow；
3）Transition loss is larger.
The patent of Patent No. CN201611155471.5 discloses a kind of extremely high frequency and turns microband connector, is related to microwave and penetrates
Frequency passive device field；Wherein, shell is located at the bottom end of connector, and housing central section is provided with step-like through-hole in the axial direction；
Pressing sleeve is fixedly mounted in the through-hole of shell, and the axial end face of pressing sleeve is contacted with the large aperture inner wall of step-like through-hole, pressing sleeve
Outside contacted with the inner wall of housing through-hole；Second insulator is fixedly mounted in the major diameter through-hole of shell, and the inner wall of pressing sleeve
It is wrapped in the outer wall of the second insulator；Contact pin is axially fixed the shaft core position mounted on pressing sleeve path through-hole, the axial direction of contact pin
The first insulator is installed in the middle part of outer wall；The front end outer wall of shell is set with attaching nut；Shell and attaching nut it
Between limited by clamp spring；It is installed with washer at the outer wall step of shell.
Although it can ensure reliability and excellent transmission, the sensitivity of its structure is still very low, coupling bandwidth
Wider, excessive loss is also very big.
Utility model content
In consideration of it, the purpose of this utility model is to provide a kind of novel millimeter waveguide to the transition structure of micro-strip, tool
Have the advantages that structural sensitivity is high, matching strip is wide and excessive loss is small.
The technical solution adopted in the utility model is as follows：
To the transition structure of micro-strip, it includes for a kind of novel millimeter waveguide：Rectangular waveguide, medium bottom plate, air chamber,
Ripple pearl and covering of the fan conical structure probe；Described covering of the fan conical structure probe one end is set in rectangular waveguide, the other end according to
It is secondary to pass through the ripple pearl for being positioned over rectangular waveguide top surface and the medium bottom plate being positioned in ripple pearl；It is placed on the medium bottom plate free
Air cavity.
Further, it is provided with microstrip line on the medium bottom plate；The medium bottom plate is the carrier of the microstrip line.
Further, described covering of the fan conical structure probe one end is covering of the fan shape, and the other end is cone shape；The fan
One end of the covering of the fan shape of face conical structure probe is set in the rectangular waveguide；The covering of the fan conical structure probe
One end of cone shape sequentially passes through the ripple pearl for being positioned over rectangular waveguide top surface and the medium bottom plate being positioned in ripple pearl.
Compared with prior art, the utility model has the beneficial effects that：
Compared with conventional transition structure, the covering of the fan conical structure probe that the utility model uses is thicker, and justifies for covering of the fan
Pyramidal structure greatly increases the area in matching face, can play the effect that broadening is applicable in bandwidth.Meanwhile the covering of the fan circular cone
Shape structure probe size is big, and under identical processing and assembled condition, the influence of processed precision and assembly precision subtracts significantly
It is small, it is easily fabricated, it is effectively guaranteed the reliability and operability of the transition structure.In addition, the structure is applicable in wide, by
Influence to frequency shift (FS) greatly reduces, and loss is smaller when transition, is effectively guaranteed the vulnerability to jamming of the transition.
