| 摘要: |
| 为满足卫星通信中双频共口径、高集成、多波束等要求，提出了一种基于封装天线（Antenna in Package，AIP）架构的Ka频段收发共口径多波束相控阵天线。天线以双频堆叠微带单元的形式实现了收发共口径，并通过天线集成滤波器保证了收发通道的隔离度优于44 dB。在±60°范围内，64元接收阵增益优于17.4 dB，128元发射阵增益优于20.2 dB，具有良好的波束扫描性能。为获得收发多波束一片式集成，在收发（Transmitter/Receiver，T/R）组件中使用晶圆级三维系统集成封装（Three Dimensions System in Package,3D-SIP）并结合微凸点的制备技术，保证了系统级芯片（System-on-Chip,SOC）的高密度二次集成。高低频混压技术同样被应用于阵面、收发网络、控制供电链路的多层板集成。所提多波束的相控阵天线新架构具有高密度集成TR组件、多波束一体化、高效散热等特点，在卫星通信和数据链等方面具有广阔的应用前景。 |

| Abstract: |
| A multi-beam phased array antenna architecture based on antenna in package (AIP) in Ka-band is proposed to meet the requirements of dual-frequency common aperture,high integration and multi-beam in satellite communication.The antenna realizes the share-aperture of transceiver by dual-frequency stacked micro strip cell,the isolation of transceiver channel is better than 44 dB through antenna integrated filter.In ±60°,the gain of 64-element receiver array is better than 17.4 dB and the gain of 128-element transmitter array is better than 20.2 dB.And it has good beam-scanning performance.In order to obtain one-piece integration of transceiver and multi-beam,wafer-level 3D system-in-package（3D-SIP） is used in the transmitter-receiver(TR) module and combined with micro-bump preparation technology to guarantee high-density secondary integration at system-on-chip (SOC).The technique of high and low frequency hybridization is also employed for the multilayer board integration of the radiating array surface,transceiver network,and power supply control link.The proposed new architecture of multi-beam phased array antenna is characterized by high-density integrated TR components,multi-beam integration,and high-efficiency heat dissipation,etc.It has wide application prospect in satellite communication and data link. |
