Abstract

The objective of this work is to demonstrate, through simulation results, an optimized beamforming approach on an antenna array designed to operate at the Galileo frequency bands. In order to achieve this, a newly designed antenna element, which covers the whole Galileo frequency band, i.e. about 31% bandwidth, is employed. This element presents very good radiation characteristics like polarization purity and gain over a large range of scanning angles showing at the same time a reasonably good impedance matching. A 4 x 4 element antenna array is then designed with this antenna element and several simulations are performed. A beamforming algorithm developed whitin the DLR antenna group called Seqar is employed in order to calculate the optimized excitation current weights to be used by the antenna array. Finally, some results comparing the beamforming performance of the antenna array at the frequency band extremities are given and discussed.
