Electronic Devices Having Co-Located Millimeter Wave Antennas

Abstract:

An electronic device may include a phased antenna array. The array may include co-located first and second antennas formed on a dielectric substrate. The first antenna may include a first patch element and multi-layer parasitic structures. The multi-layer parasitic structures may include a first set of co-planar parasitic elements. The first set of parasitic elements may overlap the first patch element and may be separated by a gap. The multi-layer parasitic structures may include an additional parasitic element that overlaps the gap. The second antenna may include a second patch element that is co-planar with the additional parasitic patch. The second patch element may at least partially overlap one of the parasitic elements in the first set. The first and second patch antennas may collectively cover first and second frequency bands while occupying a minimal amount of space on the dielectric substrate.
