Description
- This application is the National Stage of International Application No. PCT/CN2022/076807, filed on Feb. 18, 2022, which claims priority to Chinese Patent Application No. 2021208937573, filed on Apr. 28, 2021. All of the aforementioned applications are incorporated herein by reference in their entireties.
- The present disclosure relates to the technical field of communication devices, and in particular to a Luneberg lens antenna with a position-electrically adjustable feed and a Luneberg lens antenna group.
- For a traditional Luneberg lens antenna, when a radiation angle of a feed is required to be changed by adjusting its tilt angle, tower operators are required to climb a tower to adjust a pitch angle of a clamp on site to match the optimal effect, which is time-consuming and labor-intensive. In bad weather like wind or snow, this adjusting way increases operation difficulty, and a manually adjusting way brings large error. In order to reduce operating difficulty of the operators and avoid climbing of a tower by the operators to adjust an antenna every time, there are also some Luneberg lens antennas commercially available for which a position of a feed can be electrically adjusted. As technical schemes in Chinese Patent Application No. 202020408992.2, applied by the applicant and entitled “Electrically Adjustable Luneberg LensAntenna”, this type of Luneberg lens antenna includes: a feed, a Luneberg lens, a mounting rack, and a position adjusting mechanism. A spherical surface is formed on the Luneberg lens, and the Luneberg lens is relatively fixed together with the mounting rack. The position adjusting mechanism includes a swinging rack, a driving rod, a driving base, and a transmission device. The driving rod is rotationally mounted on the mounting rack. The transmission device is also mounted on the mounting rack and configured for driving the driving rod to rotate. The driving base is connected with the driving rod, and can move in a straight line along the driving rod by rotation of the driving rod. The swinging rack is between the mounting rack and the Luneberg lens, a swinging rod is connected to the swinging rack, and a rotating end that can rotate relative to the Luneberg lens is formed on the swinging rod, so that the swinging rack can swing relative to a center of the spherical surface of the Luneberg lens. The feed is mounted on the swinging rack, and a connecting rod is hinged between the swinging rack and the driving base. This structure of realizing adjustment of a feed position by swinging of the swing rack is not stable, and the swinging rod of the swinging rack needs to be mounted by hinging, which is not convenient to assemble. Based on shortcomings of an existing Luneberg lens antenna, it is urgent to improve a structure of the existing Luneberg lens antenna.
