Abstract
In some examples, an antenna module includes a ground plane, where the ground plane couples to a ground foil of an electronic device, an antenna coupled to the ground plane, and a noise canceling circuit disposed within a cutout of the ground plane.
Claims20
An antenna module, comprising:
- a ground plane, the ground plane to couple to a ground foil of an electronic device;
- an antenna coupled to the ground plane;
- and
- a noise canceling circuit disposed within a cutout of the ground plane, wherein the noise canceling circuit comprises a resonating element.
