Abstract

The present invention relates to a conformal load-bearing antenna structure for realization of array surface heat radiation by employing an FSS and a micro heat pipe. The conformal load-bearing antenna structure at least comprises: a wave-transparent cover body unit configured to bear an external load to protect an internal antenna; and an antenna unit. The wave-transparent cover body unit and theantenna unit are subjected to hot-pressing bonding by employing heat conduction materials to form a conformal load-bearing antenna structure. A heat radiation structure formed by the micro heat pipeand the frequency selective surface (FSS) is employed to form a cover body portion, the micro heat pipe is configured to transfer heat of the antenna array surface to the skinned FSS, so that the conformal load-bearing antenna structure can effectively increase the structure rigidity and intensity while employing external high-speed air flow to achieve heat radiation, facilitates improving of theCLAS structure and the heat function characteristic, and has a frequency selection wave-transparent characteristic.

Description

technical field [0001] The invention relates to a conformal load-carrying antenna, in particular to a conformal load-carrying antenna which utilizes FSS and miniature heat pipes to realize front heat dissipation. Background technique [0002] Conformal Load-bearing Antenna Structure (CLAS) is an antenna structure that has both the electromagnetic function of the antenna and the structural load-bearing function. It can be highly integrated with the shape of the carrier and has great application prospects. [0003] Phased array antenna front The dielectric skin and filling core layer of the traditional cover are integrated structure. In the phased array antenna front project, the antenna has strict temperature difference requirements (for example, the Ka frequency band requires the front temperature difference to be ≤3°C, X The front temperature difference in the frequency band is ≤7℃), the wave-transparent cover and the filling core layer are greatly affected by temperature c...
