Description
Technical Field
The invention belongs to the technical field of waveguide coaxial converters, and particularly relates to a high-frequency high-power waveguide coaxial converter under a low-pressure condition.
Background
Probe coupling is a common conversion method from coaxial to rectangular waveguide, and as shown in fig. 1, a schematic diagram of a structure in which a coaxial probe is inserted into a rectangular waveguide is shown. The inner conductor of the coaxial line vertically extends into the cavity from the wide side of the rectangular waveguide, and can excite the electromagnetic wave of the TE10 mode in the waveguide. The coaxial line transmits a TEM mode, reverse alternating current exists in the inner conductor and the outer conductor, alternating electric charges at the end of the inner conductor generate an alternating electric field in the waveguide cavity, and electromagnetic waves are excited at both longitudinal ends of the waveguide during detection if no other additional measures exist in the device. Therefore, it is necessary to introduce a short-circuiting surface at one end of the waveguide to reflect the electromagnetic wave transmitted to the port to the other port. It should be noted that the probe excites other modes besides the TE10 mode, such as TE01, TE11, etc., and therefore the appropriate waveguide dimensions should be chosen such that other higher order modes are attenuated when close to the probe.
When the probe is used for coupling, the probe is required to excite a required mode, and the coaxial waveguide conversion device is required to transmit maximum power, namely, the probe excitation is matched with the waveguide, so that the reflection in the waveguide is minimized. The structure is analyzed in detail in guided wave field theory by klin, and the radiation resistance of the probe antenna is obtained by solving the radiation field generated by the current source in the waveguide and is expressed as:
for a lossless coaxial line for transmitting a TEM mode, the characteristic impedance is as follows:
it can be seen from the above formula that the radiation resistance of the probe and the characteristic impedance Z of the coaxial line can be obtained by properly adjusting the length d of the coaxial probe and the distance l between the short-circuit surface of the waveguide and the coaxial line 0 Equal so that most of the incident power is coupled into the waveguide.
Fig. 2 is a schematic diagram showing the distribution of the coupling electric field of the waveguide probe, in which the electric field has only y-direction component and is distributed with central symmetry relative to the a-side, and the mode value is in the form of half of a sine function. When the probe is inserted along the center of the edge a and parallel to the direction of the electric field in the waveguide, the probe is positioned at the strongest position of the electric field, and the coupling is strongest.
According to the principle, a waveguide coaxial probe coupling structure of a K frequency band is designed, low-loss waveguide-coaxial-microstrip conversion is achieved by optimizing the diameter, the length and the short section distance of the probe, and microwave energy is converted into a planar microstrip circuit (or vice versa) from a waveguide.
Modeling and simulation verification are carried out on the converter by using simulation software, as shown in fig. 3-4, a simulation model and a simulation result of the K-band waveguide-coaxial-microstrip conversion are shown, and according to the simulation result, the following steps are shown: in the frequency range of 19.5 GHz-21.5 GHz, the insertion loss of the waveguide coaxial converter is less than or equal to 0.1dB, the return loss is less than or equal to-22 dB, the insertion loss is less than or equal to 0.3dB during application according to actual manufacturing experience, and the waveguide coaxial converter has excellent transmission characteristics.
Under the condition of low air pressure, the problems of ignition and local burning of a coaxial microwave insulator in a feed-in waveguide, which are caused by high-frequency high-power transmission and conversion, are analyzed by combining the principle of low-air-pressure discharge, so that the power of a high-frequency signal fed into the waveguide from the coaxial insulator is high, and under the condition of low air pressure, the electric field intensity at the top end of the insulator exceeds the field intensity threshold value of low-air-pressure discharge, the phenomena of low-air-pressure discharge, burning and local burning of a radio frequency insulator occur.
