Description

Technical Field

[0001] The utility model relates to the technical field of horn antennas, in particular to a broadband double-ridge horn antenna. Background Technique

[0002] The horn antenna is a surface antenna, a microwave antenna with a gradually expanding circular or rectangular cross-section at the end of the waveguide, and is one of the most widely used types of microwave antennas. Its radiation field is determined by the aperture size of the horn and the propagation type. Among them, the influence of the horn wall on radiation can be calculated using the principle of geometric diffraction. If the length of the horn remains unchanged, the aperture size and the quadratic phase difference will increase with the increase of the horn flare angle, but the gain will not change with the aperture size. If it is necessary to expand the frequency band of the horn, it is necessary to reduce the reflection at the horn neck and aperture; the reflection will decrease instead with the increase of the aperture size. For example, the patent with the publication number CN217823263U discloses a double-ridge structure ultra-wideband horn antenna, which drives the horn antenna mechanism to rotate by the rotation of the restraint frame. However, this device can only adjust the left and right angles of the horn antenna and cannot adjust the pitch angle of the horn antenna, resulting in a small signal transceiver range of the device.

[0003] Therefore, the utility model provides a broadband double-ridge horn antenna. Summary of the Utility Model

The installation structure includes a support column 2, a support base 3 and an installation frame 9. The double-ridge horn antenna body 1 corresponds to the support base 3. A first ball head 6 is installed on the support base 3. A support structure and a first ball bowl 10 are installed on the installation frame 9. The first ball bowl 10 corresponds to the first ball head 6. The support structure corresponds to the support base 3. The support column 2 is rotatably connected to the installation frame 9.

[0021] In this embodiment, fixing bolts 5 are installed on both sides of the support base 3. The fixing bolts 5 are in threaded cooperation with the support base 3 and are in contact with the double-ridge horn antenna body 1.

[0022] Specifically, when the double-ridge horn antenna body 1 needs to be installed, place the double-ridge horn antenna body 1 in the support base 3, and then rotate the fixing bolt 5 so that the end of the fixing bolt 5 contacts the double-ridge horn antenna body 1, and the double-ridge horn antenna body 1 can be installed.

[0023] The support structure is a telescopic rod 12. The telescopic rod 12 is fixedly connected to the installation frame 9. The installation frame 9 is a C-shaped structure.
