绿色低碳基站天线关键技术及应用

Key Technology and Application of Green Low-carbon Base Station Antenna

针对基站天线全生命周期中碳足迹和不环保的要素,所提出绿色低碳天线解决方案的总体技术思路是设法减少基站天线内部的各种损耗和提高超宽频内的波束收敛性。按照柔性引脚互联设计理念,将产品架构由四级简化为两级架构,并开发出长腔体空气介质移相馈电网络及一体化宽带低损高效辐射单元,5G低中高频天线增益明显提升。针对生产环节的不环保要素,开发出长腔体局部镀膜工艺及低介电常数环保天线罩,实现了基站天线全生命周期的绿色低碳环保。

To address the carbon footprint and non-environmental protection factors in the whole life cycle of the base station antenna,the overall technical idea of the green low-carbon antenna solution is to reduce the internal various loss of the base station antenna and improve the beam convergence in ultra-wideband.According to the flexible pin-to-pin design concept,the product architecture is reduced from four levels to two levels.A long-cavity air-dielectric phase shifter feed network and an integrated broadband low-loss and high-efficiency radiation element have been developed,which significantly improved the gain of 5G antenna in all frequency bands.Aiming at the non-environmental protection factors in the production process,the localized coating process of the long cavity and the environmental protection radome with low dielectric constant are developed to achieve the low-carbon and green environmental protection in the whole life cycle of the base station antenna.
