High-gain multilayer dielectric composite dual-circular-polarization micro-strip array antenna

The invention relates to a high-gain multilayer dielectric composite dual-circular-polarization micro-strip array antenna, and belongs to the technical field of antennas. The high-gain multilayer dielectric composite dual-circular-polarization micro-strip array antenna comprises nine micro-strip antenna units, two groups of feed networks, a lower-layer dielectric substrate, an upper-layer dielectric substrate, a metal support, dielectric struts and a 90-degree bridge circuit. The high-gain multilayer dielectric composite dual-circular-polarization micro-strip array antenna is based on a micro-strip antenna theory, double layers of the micro-strip antenna units are capable of improving the gain of the antenna by 2dB as compared with the traditional micro-strip antenna units, the two groups of feed networks with equal amplitudes and identical phases are provided with one-dividing-into-two unequal power dividers, one-dividing-into-three equal power dividers and one-dividing-into-six equal power dividers and are reasonably arranged in limited space, and excellent amplitude and phase stability of each feed end is guaranteed; and a left-hand circular polarization mode and a right hand circular polarization mode can be implemented simultaneously, so that right hand circular polarization electromagnetic signals can be transmitted or received while left hand circular polarization electromagnetic signals are transmitted or received.
