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.
