Traditional antenna port of waveguide duplexer coupling mechanism comprises plate-like body, has first resonant cavity of high frequency and first resonant cavity of low frequency in the one side of plate-like body, in first resonant cavity of high frequency and first resonant cavity of low frequency, all has harmonic oscillator.Described plate-like body has in the one side of first resonant cavity of high frequency and first resonant cavity of low frequency cover plate, and all there is screw cover plate place and this place both sides corresponding with harmonic oscillator in first resonant cavity of high frequency, all have high-frequency tuning screw in screw.All there is screw cover plate place and this place both sides corresponding with harmonic oscillator in first resonant cavity of low frequency, all have low frequency tuning screw in screw.Between first resonant cavity of described high frequency and first resonant cavity of low frequency, there is antenna opening coupling mechanism, as shown in Figure 1, this coupling mechanism is an external metalwork, utilizes external metalwork and empty waveguide to match to realize the coupling of waveguide duplexer common waveguide mouth and antenna opening.Although adopt external metalwork can realize the coupling of waveguide duplexer common waveguide mouth and antenna opening, because external metalwork is a part that is independent of duplexer body, in assembling process, there is certain tolerance, make electrical property consistency poor.Because external metalwork is a part that is independent of duplexer body, in process of production, step is many again, and not only production efficiency is not high, and can increase production cost.On the other hand, owing to utilizing external metalwork and empty waveguide to match to realize the coupling of waveguide duplexer common waveguide mouth and antenna opening, the useful space that makes to take waveguide duplexer is many, and the bandwidth of coupling is narrower, only have 800MHz.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of antenna port of waveguide duplexer coupling mechanism.Adopt this coupling mechanism, not only can enhance productivity, reduce production costs, and can increase the bandwidth of coupling.
The problems referred to above that the present invention will solve are realized by following technical scheme:
Antenna port of waveguide duplexer coupling mechanism of the present invention comprises plate-like body, has first resonant cavity of high frequency and first resonant cavity of low frequency in the one side of plate-like body, in first resonant cavity of high frequency and first resonant cavity of low frequency, all has harmonic oscillator.Described plate-like body has in the one side of first resonant cavity of high frequency and first resonant cavity of low frequency cover plate, and there is screw at the cover plate place corresponding with harmonic oscillator in first resonant cavity of high frequency, all has high-frequency tuning screw in screw.There is screw at the cover plate place corresponding with harmonic oscillator in first resonant cavity of low frequency, all has low frequency tuning screw in screw.Between first resonant cavity of described high frequency and first resonant cavity of low frequency, there is antenna opening coupling mechanism.Be characterized in the common waveguide mouth of described antenna opening coupling mechanism on comprising between first resonant cavity of high frequency and first resonant cavity of low frequency at the bottom of chamber, there is screw at the cover plate place corresponding with common waveguide mouth, is furnished with low-and high-frequency and shares coupling tuning screw in screw.First resonant cavity of high frequency and low-and high-frequency share between coupling tuning screw, low-and high-frequency shares between coupling tuning screw and first resonant cavity of low frequency and the cover plate of high frequency waveguide mouth, low frequency waveguide mouth corresponding position on be all processed with screw, in screw, all have coupling tuning screw.
Wherein said harmonic oscillator is metal harmonic oscillator, at the bottom of the bottom of this metal harmonic oscillator and the chamber of corresponding resonant cavity, forms as one.
Take such scheme to have the following advantages:
As can be seen from the above scheme, due to the common waveguide mouth of described antenna opening coupling mechanism on comprising between first resonant cavity of high frequency and first resonant cavity of low frequency at the bottom of chamber, there is screw at the cover plate place corresponding with common waveguide mouth, is furnished with low-and high-frequency and shares coupling tuning screw in screw.Performance index difference and the destabilizing factor of having avoided using tolerance that external metalwork brings and build-up tolerance to cause.Adding the present invention need not empty waveguide mate, directly connect low-and high-frequency two ends passages, facilitated the arranging of total of waveguide duplexer, be fully used in the space of duplexer, not only make duplexer performance index high conformity, and volume dwindles greatly.Owing to not using external metalwork, in waveguide duplexer manufacturing process, reduce by a procedure again, not only improved production efficiency, and reduced production cost.In addition, due to need not external metalwork and empty waveguide match to realize the coupling of waveguide duplexer common waveguide mouth and antenna opening, the useful space that makes to take waveguide duplexer is few, the broader bandwidth of coupling, up to 2000MHz.
