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.
