Abstract :
In this paper we present a stacked annular-ring microstrip antenna that covers Galileo bands (E5a, E5b, E2) and GPS band (L2). This microstrip antenna is fed by four bow-tie apertures that improve the coupling. Broadband phase shifters and Wilkinson power combiners are used to generate the required circular polarization.
