Abstract: A broadband antenna element for wireless communications includes one or more radiator layers to receive an electrical signal and to transmit a polarized electromagnetic (EM) wave. A feed layer including a feeding mechanism feeds the electrical signal generated by a transmitter into the radiator layer. A ground layer is coupled to a ground potential of the transmitter. The one or more radiator layers, the feed layer, and the ground layer are conductor layers of a multilayer substrate that includes metal layers and dielectric layers. The antenna element transmits with a broad bandwidth centered at a frequency of about 60 GHz, and maintains the broad bandwidth and polarization purity for scan angles up to a predefined value.
