Electronic Device Antenna Arrays Mounted Against a Dielectric Layer

An electronic device comprising:

• a dielectric cover layer;
• a dielectric substrate;
• and
• an indirectly-fed microstrip dipole antenna on the dielectric substrate that is configured to convey radio-frequency signals at a frequency between 10 GHz and 300 GHz through the dielectric cover layer.

An electronic device having first and second faces, comprising:

• a housing having a dielectric rear housing wall that forms the first face of the electronic device;
• a display in the housing having a display cover layer and pixel circuitry that emits light through the display cover layer, wherein the display cover layer forms the second face of the electronic device;
• a dielectric substrate mounted to the dielectric rear housing wall;
• and
• a phased antenna array on the dielectric substrate, wherein the phased antenna array comprises a dipole antenna and a patch antenna and the phased antenna array is configured to convey radio-frequency signals at a frequency between 10 GHz and 300 GHz through the dielectric rear housing wall.
