We present results of theoretical and experimental investigations of a novel dual band right hand circularly polarized microstrip antenna array with adaptive space-time processing capability for terminal of GPS/GLONASS/GALILEO satellite navigation systems. The array structure is composed from 10 microstrip radiators excited independently via separate coaxial input ports. Two central radiating elements for two frequency bands (L1 and L2) have got circular shapes with slits and are stacked to provide compact sizes and coincidence of their phase centers. Peripheral radiators have got annular ring shapes with slits topology. The main feature of the array is its compact packaging of radiating elements that causes significant levels of electromagnetic mutual coupling. Geometric parameters of the array were selected using high-efficiency multi parametric particle swarm optimization to provide optimum performance of each radiator in the compact array packaging. Moreover, several right hand circularly polarized radiators of the array assembly were rotated around their centers to improve their characteristics and to increase the quality and effectiveness of space-time processing of adaptive antenna system. The novel design of the dual frequency right hand circularly polarized array and somewhat imperfectness of the obtained characteristics are experimentally validated.
