Abstract

In this paper, the design of a multi-band circularly polarized stacked microstrip antenna for low earth orbit (LEO) satellite communications and precise global positioning system (GPS) is proposed. The microstrip antenna for multi-band frequency is constructed by stacking two different square patches and circular polarization is obtained by different approaches. The top patch has a pair of truncated square corners, and the bottom patch is fed with two pins placed symmetrically on the two main axes. The antenna is designed to operate at L₁ (1.575 GHz±12 MHz) and LEO at two frequency ranges uplink (148-150 MHz), downlink (137-139 MHz). All the design details and numerical results will be discussed in this context.
