Broadband stacked patch radiating elements and related phased array antennas

摘要

A stacked patch radiating element includes a dielectric substrate, a ground plane on a first surface of the dielectric substrate, a patch radiator on a second surface of the dielectric substrate, a feed that is configured to connect the patch radiator to a transmission line, a solder layer on the patch radiator opposite the dielectric substrate, and a parasitic radiating element on the solder layer opposite the patch radiator. The parasitic radiating element includes a metal layer on the solder, a parasitic radiator dielectric substrate on the first metal layer opposite the solder, and a parasitic radiator on the parasitic radiator dielectric substrate opposite the first metal layer.
