Abstract

An electronic device may be provided with wireless circuitry including first and second patch antennas. The first patch antenna may include a first resonating element formed over a ground plane. The second patch antenna may include a second resonating element over the first resonating element. A cross-shaped parasitic element may be formed over the second resonating element. First and second feed terminals may be coupled to the second resonating element. An opening may be formed in the first resonating element. First and second transmission lines may be coupled to the first and second feed terminals through the opening. The cross-shaped parasitic element may include arms that overlap the first and second feed terminals. The first resonating element may cover first frequencies between 10 GHz and 300 GHz and the second resonating element may cover second frequencies that are higher than the first frequencies.

Dependent claims

An electronic device, comprising:

a stacked dielectric substrate having a first layer, a second layer, a third layer, a fourth layer, and a fifth layer, the second layer being interposed between the first and third layers and the fourth layer being interposed between the fifth and first layers;
first metal traces on the first layer, wherein the first metal traces form a first antenna resonating element for a first antenna that handles antenna signals at a first frequency that is greater than 10 GHz;
second metal traces on the second layer, wherein the second metal traces form a second antenna resonating element for a second antenna that handles antenna signals at a second frequency that is higher than the first frequency;
third metal traces on the third layer that form a parasitic antenna resonating element for the second antenna;
fourth metal traces on the fourth layer that form an antenna ground, wherein at least one slot is formed in the fourth metal traces;
a first transmission line formed from fifth metal traces on the fifth layer that are coupled to the first metal traces through the fourth layer, the at least one slot, and the first layer;
and
a second transmission line formed from sixth metal traces on the fifth layer that are coupled to the second metal traces through the fourth layer, the at least one slot, the first layer, an opening in the first metal traces, and the second layer.
