The State University of Rio Grande do Sul is one of the partners to develop a National Satellite Network Stations for remote sensor data gathering and communication in Universities and Schools. The research has focused on a Low Earth Orbit (LEO) CubeSat system, with support from the Brazilian federal government’s and Brazilian Space Research Program. Our objective is to describe the implementation of a compact, low-cost antenna solution for the National Satellite Network, operating in the 145-146 MHz band. This paper proposed a single feeding port, low profile VHF omnidirectional circularly polarized (CP) antenna. The simplicity of the design coupled with broad impedance bandwidth and axial ratio make it suitable for satellite communication terminals.
