[0002] There are two types of UHF antennas available. One is a disc-conical antenna, which is easy to carry and simple to set up, but it is omnidirectional and has poor reception signal quality compared to existing log-periodic antennas. The other is a log-periodic antenna, which is directional and has better reception signal quality, but it is heavy and inconvenient to carry, and its reconnaissance frequency band is narrow, reducing reconnaissance efficiency.

The cross-sectional shape of the connecting block 403 is hexagonal. The shape and size of the connecting block 403 are completely the same as those of the positioning groove 505. The connecting block 403 matches the positioning groove 505, so as to limit the deflection of the connecting block 403. After the connecting block 403 is connected with the positioning groove 505, the connecting block 403 will not rotate with the connecting seat 401 when the connecting seat 401 is rotated by the first antenna 1. At the same time, the connecting seat 401 rotates along the connecting block 403. The end part of the positioning block 405 and the limiting groove 4031 is spherical. When the first antenna 1 and the second antenna 2 are connected, the first antenna 1 and the second antenna 2 are in a vertical state. Then the connecting seat 401 and the connecting block 403 are connected with the positioning groove 505 and the connecting groove 502. At the same time, the clamping block 4012 slides into the inside of the arc-shaped groove 504 through the clamping groove 503, and then the first antenna 1 is rotated.The connecting seat 401 can drive the two positioning blocks 405 to move circumferentially, and the positioning blocks 405 are guided by the limiting grooves 4031 to move away from the connecting block 403, and at the same time, the spring 404 is compressed, so that the positioning blocks 405 are separated from the corresponding limiting grooves 4031. When the connecting seat 401 drives the clamping block 4012 to rotate by ninety degrees, the elastic force of the spring 404 drives the positioning blocks 405 to connect with the corresponding limiting grooves 4031. Through the elastic force of the spring 404, the rotation of the connecting seat 401 is limited, and at the same time, the first antenna 1 and the second antenna 2 are connected through the limitation between the clamping block 4012 and the arc-shaped groove 404. Similarly, when the first antenna 1 and the second antenna 2 are disassembled, the first antenna 1 is rotated in the opposite direction, and the first antenna 1 drives the clamping block 4012 to rotate by ninety degrees through the connecting seat 401. Then, the connecting seat 401 is pulled out through the first antenna 1, so as to realize disassembly.

[0043] The side of the first antenna 1 adjacent to the fixed assembly 4 can also be connected with the head section one 6, and the side of the head section one 6 adjacent to the first antenna 1 is provided with the same connecting structure 5 as the second antenna 2. The side of the second antenna 2 adjacent to the fixed assembly 4 can also be connected with the head section two 7, and the side of the head section two 7 adjacent to the second antenna 2 is provided with the same connecting structure 5 as the third antenna 3.

[0044] Specifically, when the first antenna 1, the second antenna 2 and the third antenna 3 are combined for use according to actual task requirements, the first antenna 1 and the second antenna 2 are in a perpendicular state, and the connecting block 403 on one side of the first antenna 1 is connected with the positioning groove 505, and at the same time, the clamping block 4012 slides into the arc-shaped groove 504 through the clamping groove 503, and then the first antenna 1 is rotated by ninety degrees, so that the connecting seat 401 drives the clamping block 4012 to move circumferentially along the arc-shaped groove 504 by ninety degrees, and at the same time, the two positioning blocks 405 are connected with the corresponding limiting grooves 4031 under the influence of the elastic force of the spring 404. Through the elastic force of the spring 404 and the positioning blocks 405, the rotation of the connecting seat 401 is limited, and at the same time, the first antenna 1 and the second antenna 2 are connected through the limitation between the clamping block 4012 and the arc-shaped groove 404. Similarly, the second antenna 2 and the third antenna 3 are connected, and then the antennas are supported by an external support frame. Similarly, the first antenna 1 is combined with the head section one 6, the second antenna 2 is combined with the head section two 7, and the third antenna 3 is used alone. The first antenna 1, the second antenna 2 and the head section two 7 can also be combined and used through the fixed assembly 4, and the second antenna 2 and the third antenna 3 can also be combined and used through the fixed assembly 4. In different task situations, the antennas can be quickly erected and deployed, so as to meet the actual task requirements of segmented carrying and erection, and the task efficiency and antenna erection time are improved.
