Problems solved by technology

[0005] Although the use of connectors for antenna feeding has many advantages, there are some insurmountable disadvantages in this way: first, the connector will bring unnecessary loss, and the loss will increase as the operating frequency increases. Big
Second, in large-scale arrays, the use of a large number of connectors will affect the reliability of the array
Third, the use of connectors for connection can no longer meet the heat dissipation requirements of the array
However, the traditional feeding method using connectors only ensures the transmission of antenna radio frequency signals, and cannot meet the heat dissipation requirements of array antennas.

Abstract

The invention relates to the technical field of an array antenna, and discloses a low-thermal-resistance connector-less feed array antenna; the array antenna is characterized by specifically comprising a printed board, an antenna unit and a transceiving assembly, wherein a metalized through hole is formed in the printed board; one end of the metalized through hole is connected with the antenna unit through conductive adhesive while the other end of the metalized through hole is connected with the transceiving assembly; and feeding is performed to the antenna array through the metalized through hole. A connector is not required to realize high-frequency signal transmission between the array antenna and a feed network, so that signal transmission loss caused by the connector is eliminated, and the array unit failure caused by the failure of the connector is avoided as well; therefore, the electrical performance and the reliability of the array antenna are improved; and the invention also discloses an implementation method for the low-thermal-resistance connector-less feed array antenna.

Description

technical field [0001] The invention relates to array antenna technology, in particular to an array antenna with low thermal resistance and no connector for power feeding and a realization method thereof, without a connector, thereby improving the durability and reliability of the electronic equipment of the whole machine. Background technique [0002] In order to ensure the high-performance and high-reliability interconnection between the radio frequency cable and the antenna unit, large-scale array antennas generally use radio frequency connectors for unit feeding. Commonly used RF connectors include N-type connectors, SMA connectors, etc. [0003] For large-scale array antennas, on the premise of ensuring power capacity, the RF connectors mentioned above are often used to connect the antennas to the transceiver components. One end of the connector is connected to the transceiver component, and the other end is excited by current or coupling to inject energy into the ante...
