Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
The terms of direction and position of the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., refer to the direction and position of the attached drawings. Accordingly, the use of directional and positional terms is intended to illustrate and understand the present invention and is not intended to limit the scope of the present invention.
As shown in fig. 1 to fig. 3, an embodiment of the present invention is an RRU with an integrated antenna, and includes a body 1 and an antenna 2; wherein,
a groove 11 is formed on the body 1;
the antenna 2 is fixedly arranged in the groove 11 and comprises a circuit board 21 provided with a feed network and at least one antenna radiating unit 211 arranged on the circuit board 21;
the circuit board 21 is electrically connected with the body 1 through a connecting piece 212;
the bottom wall 111 of the recess 11 is formed as a radiation plate of the antenna 2.
It will be appreciated that the RRU is tightly integrated with the antenna 2 and its body 1 with the bottom wall 111 of the recess 11 formed as a radiating plate of the antenna 2, so that the antenna 2 no longer needs to be provided with a separate radiating plate, thus reducing the overall volume and weight.
In order to reduce the attenuation degree of signals in the transmitting and receiving processes, certain processing requirements are set on the surface finish of the bottom wall 111 of the groove 11, and the surface finish requirement is less than or equal to 1 mu m.
Because the circuit board 21 generates certain heat when the antenna 2 is in use, in order to improve the heat dissipation of the circuit board 21 and prolong the service life of the circuit board, at least one support column 112 is arranged between the circuit board 21 and the bottom wall 111 of the groove 11, so that a gap with a certain distance favorable for heat dissipation is formed between the circuit board 21 and the bottom wall 111 of the groove 11, and the circuit board 21 and the bottom wall 111 of the groove 11 are fixed by screws, thereby avoiding the damage caused by the falling of the antenna 2 in the transportation or use process.
