Description

Technical Field

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. A component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy using electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. An array antenna is an antenna system composed of many identical single antennas (such as symmetrical antennas) arranged in a certain pattern, also known as an antenna array.

[0003] With the development of technology, small antennas are widely used. Most of the existing single array antennas have integrated mainboards. When replacing a single LTE antenna, the mainboard needs to be replaced as a whole, which is inconvenient. To address the above problems, we have launched a small LTE single array antenna.

When replacing, the number of installation medium substrates can be fixed according to usage requirements, which is more convenient to use. It solves the technical problem that most of the existing single-array antennas have an integrated mainboard, and a single LTE antenna needs to replace the mainboard as a whole when replacing, which is inconvenient to operate.

[0010] In a preferred solution, fixing blocks are symmetrically fixed on both sides of the installation medium substrate, and fixing grooves are symmetrically opened on the top of the No. 1 mainboard and on both sides of the installation groove. The fixing blocks extend into the inside of the fixing grooves, and positioning holes are equidistantly opened in the fixing blocks and the inside of the fixing grooves.

[0015] The through slot is arranged to facilitate the wiring installation of the built-in antenna in the corresponding limit slot, making the connection more convenient.

[0016] The small LTE single array antenna provided by the utility model has the following advantages:

[0017] First, by setting up an installation medium substrate and a built-in antenna, the built-in antenna is fixed in the corresponding limit groove by equidistant arrangement as required, and the arranged positioning block extends to the inside of the positioning groove and is glued by glue. When replacing, the number of installation medium substrates can be fixed according to the use requirements, which is more convenient to use and solves the technical problem that most of the existing single-array antennas have an integrated mainboard, and a single LTE antenna needs to replace the mainboard as a whole when replacing, which is inconvenient to operate.
