Abstract
Disclosed herein is a multilayer planar array antenna. The antenna includes a waveguide, a first dielectric layer, a radiating unit, a second dielectric layer, parasitic elements, and a feeding cover unit. The waveguide is configured to transmit signals. The first dielectric layer stacked on the waveguide. The radiating unit is formed in such a way that a plurality of radiating elements and a plurality of radiating element feeding portions, which are arranged on the first dielectric layer, are formed thereon, so that a dually polarized wave is transmitted and received in a single plane. The second dielectric layer is stacked on the radiating unit. The parasitic elements are formed on the second dielectric layer to correspond to the respective radiating elements. The feeding cover unit is formed on the parasitic elements to correspond to the plurality of radiating element feeding portions.
