摘要： 以目前单兵手持终端的小型化、高集成度需求为应用牵引，围绕基于单兵手持终端天线系统的平面化集成设计展开研究。针对目前单兵手持终端天线系统独立封装、集成度低的问题，研制了包含收发自组网、卫星导航及卫星通信四个天线的平面化天线系统，采用平面印刷单极子代替具有三维结构的收发自组网天线，采用线极化的水平偶极子替代常用的三维圆极化螺旋天线。仿真和实测结果表明，该平面化四天线系统可以实现自组网频段内的水平全向的覆盖，在卫星导航及通信频段内可以覆盖上半空间，可被用于单兵手持终端设备中以提高设备的集成度。

Design of planar four-antenna system for single soldier handheld terminal

Abstract： The planar integration design of the antenna system for soldier terminals is presented in this paper based on the requirements of the miniaturization and high integration. A four-antenna system including recieving and transmitting Ad-Hoc network antennas, satellite navigation and communication antennas is proposed to solve the 3D packaging and low-integration problems. The conventional 3D Ad-Hoc network antennas and circular polarized helix antennas are replaced by planar printed monopoles and horizontal dipoles with linear polarization, respectively. Simulated and Measured results show that the planar four-antenna system realizes onmidirectional radiation in horizontal plane in Ad-Hoc network frequency band and upper space coverage in satellite navigation and communication band. This antenna system can be applied in soldier terminals to improve its integration.
