Description

Technical Field

[0001] The utility model belongs to the technical field of communication equipment, and in particular relates to a terminal antenna and equipment integrating low-orbit and sky-communication satellite communications. Background Art

[0002] Both low-orbit satellites and Tiantong satellites are used in satellite mobile communications. At present, the research on low-orbit satellite antennas and Tiantong satellite antennas in the industry has gradually matured, and is gradually developing in the direction of miniaturization, wide beam and multi-mode.

[0003] In the prior art, low-orbit satellite antennas and Tiantong satellite antennas generally work separately. If the communication equipment needs to work in Tiantong satellite communication mode and low-orbit satellite communication mode respectively, the low-orbit satellite antenna and Tiantong satellite antenna need to be installed separately, resulting in the antenna occupying a larger volume on the communication equipment, which is inconvenient to use. Therefore, the integration of low-orbit satellite antennas and Tiantong satellite antennas has become a technical problem to be solved in this field.

The terminal antenna adopts a pull-out structure, in which the active radiator is arranged inside the fixed radiator, and the working mode of the terminal antenna is switched by pulling. When working in Tiantong mode, the upper radiator is located on the inner side of the lower radiator and produces strong coupling, resulting in a decrease in the radiation efficiency of the Tiantong antenna at this time.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further explained below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the implementation methods described below.

[0029] See also Figure 1 and Figure 2 , showing a schematic diagram of a terminal antenna integrating low-orbit and Tiantong satellite communications described in the utility model, the terminal antenna described in the utility model includes: a fixed radiator 1, on which a fixed radiator arm 11 is arranged; a feeding base 2, the feeding base 2 is fixedly connected to the fixed radiator 1 and electrically connected to the fixed radiator arm 11; a movable radiator 3, the movable radiator 3 is rotatably connected to the fixed radiator 1, and a movable radiator arm 31 is arranged on the movable radiator 3; when the movable radiator 3 is rotated so that the movable radiating arm 31 is in contact with the fixed radiating arm 11, the terminal antenna is in a low-orbit satellite communication mode; when the movable radiator 3 is rotated so that the movable radiating arm 31 is not in contact with the fixed radiating arm 11, the terminal antenna will be in a Tiantong satellite communication mode.

[0030] In this embodiment, the characteristics of the low-orbit satellite antenna and the Tiantong satellite antenna that both radiate left-handed circular polarization and have a frequency difference of 500MHz are utilized. The terminal antenna is designed in combination with the idea of ​​shared radiator and frequency reconfigurability, and the low-orbit satellite terminal antenna and the Tiantong satellite terminal antenna are integrated into a whole. While reducing the volume of the antenna on the terminal device, this embodiment rotatably connects the active radiator 3 with the fixed radiator 1, so that the working mode of the terminal antenna can be switched by rotating the active radiator 3 during use, thereby avoiding the problem in the prior art that when the adjustable handheld terminal antenna integrating low-orbit and Tiantong satellite communications is in Tiantong mode, the upper radiator is located on the inner side of the lower radiator and produces strong coupling, resulting in a decrease in the radiation efficiency of the Tiantong antenna at this time, and the terminal antenna structure strength decreases due to multiple pulling and pulling operations during use, which brings about technical problems of insufficient reliability.

[0031] During use, the feeding base 2 is used to feed the terminal antenna. When the movable radiator 3 is rotated so that the movable radiating arm 31 on the movable radiator 3 is in contact with the fixed radiating arm 11, the movable radiating arm 31 and the fixed radiating arm 11 will radiate together, so that the terminal antenna is in a low-orbit satellite communication mode; when the movable radiator 3 is rotated so that the movable radiating arm 31 and the fixed radiating arm 11 are not in a contact connection state, the fixed radiating arm 11 will radiate alone, so that the terminal antenna is in a Tiantong satellite communication mode.

[0032] Furthermore, the movable radiator 3 and the fixed radiator 1 may be detachably connected so that the movable radiator 3 and the fixed radiator 1 can be disassembled during use to facilitate maintenance and adjustment of the terminal antenna. It should be noted that those skilled in the art may select a detachable connection method between the movable radiator 3 and the fixed radiator 1 according to actual production and use requirements, and this is not specifically limited in this embodiment.

[0033] Optionally, refer to Figure 3 The fixed radiator 1 described in the utility model includes a fixed part 12, and the fixed part 12 includes a feeding end 121 and a connecting end 122 which are arranged in opposite directions along its axial direction; a fixed radiating arm 11 is arranged on the outer wall of the fixed part 12, and the fixed radiating arm 11 extends from the feeding end 121 to the connecting end 122; a feeding base 2 is fixedly connected to the feeding end 121; and a movable radiator 3 is rotatably connected to the connecting end 122.

The feeding base 2 is fixedly connected to the feeding end 121 to fix and support the fixed part 12 and feed the fixed radiating arm 11; the movable radiator 3 is rotatably connected to the connecting end 122.

[0035] Furthermore, the fixing portion 12 may be made of a flexible circuit board. It should be noted that those skilled in the art may select the material of the fixing portion 12 according to actual production and use requirements, and no specific limitation is made in this embodiment.

Specifically, the movable radiating arm 31 can be arranged on the inner wall or the outer wall of the movable portion 32. When the movable radiating arm 31 is arranged on the outer wall of the movable portion 32, an elastic conductive member should be provided at one end of the movable radiating arm 31 close to the fixed portion 12. During use, when the movable portion 32 is rotated to put the terminal antenna in the low-orbit satellite communication mode, the elastic conductive member is in contact and connection with the fixed radiating arm 11 to achieve contact and connection between the movable radiating arm 31 and the fixed radiating arm 11. Specifically, the connection method between the elastic conductive member and the movable radiating arm 31 can be selected as welding, screw or bolt fixing.

Therefore, in this embodiment, a connecting conductive member 4 is provided on at least one of the movable radiation arm 31 and the fixed radiation arm 11, and when the movable part 32 is rotated to put the terminal antenna in the low-orbit satellite communication mode, the connecting conductive member 4 is in contact with the fixed radiation arm 11 to achieve contact connection between the movable radiation arm 31 and the fixed radiation arm 11.

Specifically, the first radiating arm 111, the third radiating arm 311, the second radiating arm 112 and the fourth radiating arm 312 are all four, so that the radiation structure formed by the fixed radiator 1 and the active radiator 3 is an eight-arm spiral structure. The length of the second radiating arm 112 is less than the length of the first radiating arm 111, and the length of the fourth radiating arm 312 is less than the length of the third radiating arm 311, so as to realize the low-orbit satellite communication function.
