Abstract

The design of a Compact Dual-band Equatorial helix antenna is presented. These antennas are used for Telemetry, Tracking, and Control (TTC) of satellites from the terrain base station. A simulation-optimization process is presented, a simulation tool named MONURBS is linked with a well-known multi-objective algorithm (NSGA-II) in order to design and optimize the parameters of the antenna. The size of the antenna that fulfills radiation patterns needed for the communication are obtained using simulation together with a multi-objective algorithm. In this work, a comparison with previous designs and the antenna prototype are be presented showing that this approach can achive solutions expediting the process.
