Abstract

The present invention relates to an integrated horn antenna device, which is provided with a signal input connector and a horn antenna that are respectively arranged at an input end and an output end of a waveguide. An air resonance chamber connected to the output end is formed inside the waveguide. A medium waveguide is configured at a connection part of the air resonance chamber of the waveguide and the output end, in which a medium launch cone with a passivated vertex is formed on the medium waveguide. An output end of the horn antenna is configured with a radome lens. Since the vertex of the medium launch cone is passivated, a radiation field pattern can be effectively improved. In addition, since signals pass through the air resonance chamber first and then pass through the medium launch cone, impedance can be converted twice at a smaller range, such that antenna bandwidth can be maintained easily. Furthermore, the radome lens can focus a plane wave of cone antenna radiation. Therefore, directivity can be effectively improved, such that half beam width is narrower to increase interference immunity of measurement environment.

Description of the Invention: [Technical Field] The present invention relates to an integrated horn antenna device, and more particularly to an antenna which can improve the radiation pattern and increase directivity. [Prior Art] In recent years, the industrial development has been scientific and technological. In order to monitor the material level in the storage tank in real time, a radar antenna device is installed on the top of the tank. The radar antenna device can emit a microwave signal meter number. When the signal contacts the material, a The reflected signal is calculated by the frequency difference between the transmitted signal and the received signal and the time difference, thereby calculating the distance to the object to be tested. The antenna structure of the existing radar antenna device is shown in US Pat. No. 6,335,418, which is shown in Fig. 5, which is provided with a signal input connector 92' at the input end of a waveguide 91. The output end of the waveguide 91 is provided with a The funnel-shaped horn antenna 93, and the inside of the waveguide 91 is formed with a cavity in which the column medium 94 is filled. The surface of the cylindrical medium 94 is output from the waveguide 91. To the funnel-shaped horn antenna 93 & is formed with a linear conical medium converter 95 (shown in Figure 16), and the cylindrical medium 94 can be composed of Teflon 2F (pTFE). However, since the antenna structure has a sharp angle of 951 vertices of the linear conical medium conversion, the light-shooting field type of the linear conical medium converter 95 tends to cause the tip field type to affect the antenna light-emission efficiency at the peak end of the main beam; And because the cavity system in the waveguide 91 is filled with the cylindrical medium 94, when the signal is input from the signal input connector 92 to the waveguide 91, the signal will enter the cylindrical medium 94 directly and input by the cylindrical medium 94. To linear cone dielectric launch cones 95, 201232919, however, the impedance of the signal input connector 92 (50 ohms) is typically much smaller than the air dielectric impedance (377 ohms) in the horn antenna 93, with a small impedance directly from the signal input connector 92. It is not easy to convert the large impedance of the air medium into the horn antenna 93 and the impedance is too large to reduce the antenna bandwidth. All of the above are the ideals of the existing technology. It needs to be further reviewed and a feasible solution is sought. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an integrated horn antenna device that is mainly used to improve a waveguide and a medium emission cone in an antenna, so that the integrated horn antenna device can achieve good impedance conversion.

The present invention can achieve the following advantages and effects by the foregoing technical means: Since the apex of the medium transmitting cone is a non-sharp angle, the main beam tip can be prevented from having a prominent field type, so that the radiation field pattern can be effectively improved; And because the signal first passes through the air resonance cavity and then passes through the medium emission cone, the impedance can be relatively easy to maintain the antenna bandwidth through two smaller amplitude conversions; and because the radome lens of the present invention can radiate the plane wave of the cone antenna Focusing, it can effectively improve the directivity, make the half beam width narrower, and increase the anti-interference to the measurement environment.

When the signal is emitted from the medium emission cone 50, it is a plane wave, and the signal passes through the eccentric radome. After the lens 60, both the plano-convex lens 60 of FIG. 9 and the plano-concave lens 60A of FIG. 1 will be biased and focused on one point. When the signal is input from the signal input connector 20 (impedance 50 ohms) to the waveguide 1〇 When the signal enters the air resonance cavity 11 (impedance 1〇〇~15〇 ohms), it enters the dielectric waveguide 40 from the air resonance cavity 11 and is transmitted by the dielectric guide 40 to the medium emission cone. Body 50 is emitted to the air medium (resistance 377 ohms), so that the impedance of the signal may be converted by the two smaller amplitude, easier to maintain the antenna bandwidth. Because the apex of the medium emission cone is not a sharp angle, and the protruding end field of the main beam is prevented from being prominent, the radiation pattern can be effectively improved; and since the signal first passes through the air resonance cavity and then passes through the medium emission cone, The impedance can be easily maintained by two smaller amplitude conversions; and because the radome lens of the present invention can focus the plane wave radiated by the cone antenna, the directivity can be improved and the half beam width can be narrowed. Increase the immunity to the measurement environment. And compared with the outer diameter of the peripheral wall from the bottom end to the top of the decreasing amplitude is a linear medium emission cone, the peripheral wall wall surface from the top to the bottom end forming a concave arc surface of the medium emission cone can be 1, the antenna bandwidth The antenna of the linear medium emission cone has a wide bandwidth. 2. The ratio of the radiation field type side lobes of the antenna to the main lobes is increased. Therefore, the side beam can be depressed, so the signal is concentrated in the main beam, which can further improve the directivity. Further improve the efficiency of radiation.
