title = "A Dual-Band Dual-Circularly Polarized Shared-Aperture Microstrip Antenna for LEO Satellite Communications",
abstract = "This paper presents a dual-band dual-circularly polarized shared-aperture antenna designed for low Earth orbit (LEO) satellite communication systems. The antenna adopts a stacked patch microstrip configuration with feeding networks consisting of power dividers and phase shifters integrated on the antenna backplane to achieve dual circular polarization. Simulation results demonstrate that the proposed antenna achieves left-handed circularly polarized (LHCP) radiation at 19 GHz and right-handed circularly polarized (RHCP) radiation at 29 GHz, with relative bandwidths of 16.7\% and 20.2\% in the K-band and Ka-band, respectively. The measured port isolation remains below -19 dB and -30 dB for the corresponding frequency bands. This antenna configuration can serve as a fundamental element for shared-aperture phased array antennas, providing an efficient antenna solution for LEO satellite communication applications.",
