Abstract
The paper presents results of research and development of a novel dual band circularly polarized microstrip antenna array with adaptive space-time processing capability for applications in satellite navigational systems GPS/GLONASS/GALILEO. Geometry of the proposed antenna array was optimized for the operation in two frequency bands allocated for satellite navigational systems. The developed array structure is composed from ten microstrip radiators independently excited via separate coaxial input ports‥ The geometric parameters of the array were selected via multi parametric particle swarm optimization method to provide optimum performance of each radiator in compact array packaging.
