The invention relates to an antenna mounting device used for radio communication equipment, which comprises a fixed part, a first movable part and a second movable part, wherein the fixed part is fixedly arranged on the radio communication equipment; the first movable part can be movably connected with the fixed part; the second movably part can be rotatablely connected to the first movable part, and is provided with an arrangement area capable of being used for arranging an antenna; and the first movable part and / or the second movable part can extend out of an accommodating space of the radio communication equipment. The antenna mounting device solves the problems that a built-in antenna of the radio communication equipment provided with a metal shell cannot receive and transmit signals, and simultaneously, when the antenna is not needed, the antenna mounting device is accommodated inside a body of the radio communication equipment, and the antenna mounting device is convenient to carry.

The invention discloses a backpack type mobile communication base station, which comprises a base station backpack and a balloon antenna. The balloon antenna and the base station backpack are connected by wires. Two-way blower, one end of the two-way blower is connected to the airbag, and the other end can be connected to the balloon antenna through the socket. The helium in the antenna and the airbag can communicate with each other, and the same gas can not only lift the balloon antenna but also protect the base station, so there is no need to carry a helium tank for backup.

The disclosure provides a terminal casing and a terminal, which belong to the technical field of communications. The terminal housing includes a back cover, a radio frequency module, and an antenna array, and the radio frequency module is connected to the antenna array; the back cover includes a first area and a second area other than the first area, and the first area is connected to the second area through an insulating material; A region includes a plurality of antenna elements, each antenna element is made of a conductive material, and any two adjacent antenna elements are connected through an insulating material, so that the plurality of antenna elements form an antenna array. The present disclosure proposes a design scheme of an antenna array. The antenna array is located on the terminal housing and is not covered by the back cover. The signal of the antenna array is blocked and shielded, which ensures the performance of the antenna array, gets rid of the restriction that the back cover can only be made of non-metallic materials, and has a wider application range and improved flexibility.

The invention provides an antenna mounting device for radio communication equipment, comprising a fixed mechanism fixed on the radio communication equipment, a first movable mechanism, and a second movable mechanism rotatably connected with the first movable mechanism and used for disposing an antenna, wherein the fixed mechanism comprises an elastomer capable of applying force to the first movable mechanism in the sliding direction, and a blocking component with a locking position. The first movable mechanism is in fit with the blocking component, can be blocked at the locking position by overcoming the force applied by the elastomer or move out from the locking position, and is in sliding fit with the fixed mechanism under the deformation force of the elastomer. The second movable mechanism can extend out from the containing space of the radio communication equipment, thereby solving the problem that a built-in antenna of the radio communication equipment with a metal shell cannot receive and transmit signals; moreover, the antenna mounting device can be contained in the body of the radio communication equipment when being not used so as to be convenient for carrying.
