Description
Technical field
The utility model relates to the waveguide duplexer, particularly relates to a kind of waveguide duplexer antenna opening coupled structure.
Background technology
In modern microwave and millimeter wave system, filter and duplexer are one of vitals, are used for channel selecting and Signal Separation, the good and bad quality that directly influences whole communication system of its performance.Low Insertion Loss, small size, high-frequency selectivity, low cost and designing fast etc. becomes the key technology requirement of filter and duplexer, and conventional filter and method for designing are difficult to adapt to the needs of modern development.The broad sense Chebyshev filter has sharp-pointed frequency selectivity, and group delay that again can flat filter can also form multiband filter, therefore is widely used in various microwave and millimeter wave system.Its flexible design, the simulation optimization difficulty is big.Chinese scholars uses multiple numerical algorithm that it is carried out the all-wave modeling, so that quick precise design broad sense Chebyshev filter and waveguide duplexer, wherein, obtain domestic and international research worker's great attention because of advantages such as its precision height, fast operations based on the pattern matching method of strict field theory.Microwave system below 6GHz adopts the coaxial type duplexer mostly, then waveguide type duplexers that adopt more than the 6GHz more.
And waveguide is meant the hollow metal tube that the endless of various cross sectional shapes is straight, the medium situation of filling does not all change along tube axial direction in the structural material of its cross sectional shape and size, tube wall and the pipe, and it is limited in the metal tube electromagnetic wave that is directed fully along its axial propagation.It is applicable to the signal of transmission 3-300GHz frequency range, characteristics are that conductor losses and dielectric loss are little, power capacity is big, radiationless loss and simple in structure, be easy to make.The rectangular waveguide duplexer is made up of the series of rectangular waveguide resonant cavity basically, forms inductive coupledly between the adjacent chamber by window, and this duplexer is generally adopted because of its workability.
Antenna opening is the emission filter in the waveguide duplexer and the common port of receiving filter, adopts the mode of the asymmetrical T-junction of mechanical structure to form more, transmits and received signal in order to effective separation, and both are worked and non-interference simultaneously.But when duplexer works in the lower microwave band of frequency when especially being lower than 10GHz, the size of T-junction usually can be very big, can't satisfy the overall dimension requirement of some product.
In traditional waveguide dress multiplexer, the way of realization of antenna opening coupling is to realize with the form that copper wire bending or copper rod weld, the antenna opening coupling assembly complex manufacturing technology of these implementations, cause waveguide duplexer antenna opening degree of coupling consistency and stability phenomenon such as bad, brought problems to batch process.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of waveguide duplexer antenna opening coupled structure for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of waveguide duplexer antenna opening coupled structure, it is characterized in that, comprise rectangular ridge and the copper sheet of being located at antenna opening, the middle part of described rectangular ridge is provided with a rectangular channel, the bottom of this rectangular channel is provided with a rectangular aperture, the top of described rectangular channel is provided with a bridge, the two ends of this bridge are connected with the middle part, two narrow limits at rectangular channel top respectively, the middle part of described bridge is provided with screw, the two ends of described copper sheet are and turn down shape vertically upward, this copper sheet by a screw in the lower surface of bridge.
The middle part of described bridge be provided with one with the suitable mounting groove of copper sheet, described screw is located in the mounting groove.
The width of described copper sheet is 3mm, and thickness is 0.8mm.
Compared with prior art, the utlity model has following advantage:
1, consistency:
It all is home built that the copper wire bending is welded its manufacturing process with copper rod, though can come measurement size with vernier caliper, the tolerance of slide calliper rule adds the tolerance of manual bending.For the first time, be difficult to guarantee consistency with the size of making for the second time deviation to some extent just; The utility model is the manufacturing of machine work form, so can guarantee the consistency of antenna opening assembly fully;
2, stability:
Copper wire is bent into ring-type and copper rod, and to weld these two kinds of its coupling assemblies of form all very little with the housing surface distance, causes short circuit phenomenon in the high and low temperature state easy deformation, causes the product electrical performance indexes bad, can influence the stability of product like this; The junction design matrix draw-in groove of rectangular ridge of the present utility model and copper sheet can be combined closely with copper sheet, and it is fastening to cooperate hold-down screw to carry out again, easy assembling simple in structure, and stability is conspicuous;
3, reliability:
In debugging copper wire is housed and is bent into ring-type and copper rod when welding the product of these two kinds of forms, the adjustor adjusts back (promptly collude copper wire or adjust the copper rod seat) to the antenna opening assembly, under the situation that product jolts when high low temperature or vibrations and transportation, the performance of the product phenomenon that is short-circuited probably; If failure welding in copper wire that in the product of power requirement is arranged, occurs colluding or the manufacturing process, also may emergent power the phenomenon of sparking.
The utility model can reduce interacting of the duplexer low-and high-frequency two ends degree of coupling, and the coupled modes of copper sheet can strengthen low-and high-frequency two ends degree of coupling power, and mute simultaneously bonding jumper and rectangular ridge also spin by screw thread; Can not be affected under such duplicate protection jolts product when high low temperature or vibrations and transportation the situation yet; Also can reduce greatly for the probability that spark phenomenon takes place in the product that power requirement is arranged.
