  • CIRCULARLY POLARIZED ANTENNA FOR SATELLITE COMMUNICATION
    Publication number: 20100245204
    Abstract: A circularly polarized antenna includes a dielectric substrate having a first via array in the form of a cylindrical cavity, a micro-strip circular patch antenna located at the center of the cylindrical cavity and formed on the dielectric substrate to radiate a signal, and a rectangular dielectrically loaded waveguide having a second via array and serving to feed the signal to the micro-strip circular patch antenna. Accordingly, the circularly polarized antenna prevents impedance mismatch between the micro-strip antenna and the dielectrically loaded waveguide and broadens an impedance bandwidth thereof.
