Abstract
The invention relates to a miniaturized planar micro-strip bridge, which is used for the design of micro-strip line radio frequency circuits in radio frequency microwave field. The purpose of the invention is to provide a bridge suitable for a micro-strip radio frequency circuit to enable two micro-strip lines to intersect with each other in a planar structure without interfering each other. Design parameters for the micro-strip lines in the bridge are fixed, no additional calculation is required and the design parameters can facilitate engineering realization. The invention mainly has the advantages that the dimension is small and the electrical length is only 90 degrees multiplies 90 degrees; the design and the realization are easy and the characteristic impedance is constant; the price is low, no additional devices are required and the number of layers of the circuit board is reduced; and the structure is the planar structure and the intersection of the two micro-strip lines is realized under the condition that no discontinuity is introduced in.
Description
Technical field
The present invention relates to the microstrip line radio circuit design for frequency microwave field.
Background technology
Microstrip circuit is conventional implementation method in radio circuit design.In the process of microstrip circuit wiring, often can there is the situation that two microstrip lines intersect.In engineering practice, article two, when microstrip line intersects, the general multilayer board that adopts three-dimensional structure is realized, a microstrip line wherein need to pass through another microstrip line from other layers by via hole, this certainly will bring the discontinuity of circuit impedance, affect the performance of transmission line, Enhanced Radiation Reduced Blast harassing and wrecking, the antijamming capability of reduction circuit.The present invention relates to a kind of planar micro-strip bridge, can allow two microstrip lines glitch-free intersection in planar structure pass through.Its Miniaturization Design and simple implementation structure make this gap bridge be easy to realize on micro belt board.Planar structure has reduced the cost of manufacture of circuit board, has eliminated discontinuity.
Prior art is retrieved to discovery, there is no at present related application and mandate.To finding in the retrieval of document, Wight, the people such as J.S. have proposed a kind of plane bridge structure on " IEEE Transactions on Microwave Theory and Techniques " periodical, but volume is larger.Chen, the people such as Y. have proposed a kind of small-sized gap bridge of symmetrical structure on " IEEE Transactions on Microwave Theory and Techniques " periodical, but design formula is comparatively numerous and jumbled.Chiou.Y.C. wait people on " IEEE Microwave and Wireless Components Letters " periodical, to propose the micro-strip bridge of another kind of miniaturization, but there is equally complicated design formula, be not easy to application to engineering practice.
Summary of the invention
The object of this invention is to provide a kind of micro-gap bridge with radio circuit that is applicable to, two microstrip lines can glitch-free intersection be passed through in planar structure.Microstrip design parameter in gap bridge is fixed, and do not need extra calculating, and design parameter is easy to Project Realization.
The present invention is achieved through the following technical solutions: port (port one, port 2, port 3, port 4), lateral contour microstrip line (T
h), longitudinally profile microstrip line (T
v), center microstrip line (T
m), open circuit minor matters microstrip line (T
os).
Described port is gap bridge and the connectivity port of microstrip line.Wherein, port one and port 3 form a path, are responsible for transmitting a microstrip line; Port 2 and port 4 form another path, are responsible for transmitting another microstrip line.Article two, isolation mutually, not impact between path.
Described horizontal microstrip line, totally 4 sections, for forming four sections of transversely arranged microstrip lines of peripheral profile.Its electrical length is 45 °, and characteristic impedance is 50 Ω.
Described longitudinal microstrip line, totally 2 sections, for forming the microstrip line of two sections of longitudinal arrangements of peripheral profile.Its electrical length is 90 °, and characteristic impedance is 50 Ω.
Described center microstrip line, for being positioned at longitudinal microstrip line of structure centre.Its electrical length is 90 °, and characteristic impedance is 25 Ω.
Described open circuit minor matters microstrip line, totally 8 sections is 8 sections of open circuit minor matters of inside configuration.Its electrical length is 45 °, and characteristic impedance is 50 Ω.
Microstrip line in described gap bridge can be used strip line, co-planar waveguide or the line of rabbet joint to substitute and form plane strip line, co-planar waveguide or line of rabbet joint gap bridge.
The present invention is that a kind of miniaturization, novelty, plane simple, that be easy to realize are passed a bridge.Its main feature is: size is little, and electrical length is only 90 ° × 90 °; Be easy to Design and implementation, characteristic impedance is normal value; Price is low, does not need extra device, and can reduce the number of plies of circuit board; Planar structure realizes the intersection of two microstrip lines in the situation that not introducing discontinuity.
