Sažetak
The benefits of circular polarization range from the reduction of the Faraday rotation effect in satellite systems, to the multipath rejection and independence of antenna orientation in the growing applications of unmanned aerial vehicles. Here, the focus is on the septum feed design which can be implemented in the ground dish or horn antennas, or used standalone as an antenna. It provides left and right hand circular polarization and better circular polarization characteristics within the wide frequency band, in relation to the given literature. The analysis and optimisation of the septum feed is done using the analytical approach, numerical simulations and measurements, and the results show that satisfying impedance and radiation parameters are achieved in the wide frequency band from 5.1 - 6.0 GHz.
