MetadataShow full item record
AbstractRecently, small satellites such as Cube Satellites (CubeSats) have played an important role in modern communication and applications like imaging, remote sensing, education, wide-area measurements, deep-space research, and deep-space observations and communications. CubeSat antenna has primary functions in telemetry and command, communication, navigation, and inter-satellite links (ISL) operations. This paper investigates the radiation characteristics of proposed arrays of quadrifilar helix antenna as an application on a CubeSat in L-band. Firstly, the problem is formulated using the moment method for a four-element array on top of a CubeSat is considered. Then, the radiation patterns, array gain, and axial ratio are depicted. Finally, the characteristics of a cavity-backed four-element quadrifilar helical antenna on top of a CubeSat are investigated. Simulation results show that the antenna gain increases using the cavity while the axial ratio slightly decreases.
