Electronic device printed circuit board patch antenna
First Claim
1. An electronic device, comprising:
- a housing having a metal portion that serves as an antenna ground for an antenna;
a printed circuit having a metal layer that forms an antenna resonating element for the antenna; and
a capacitive touch sensor;
a glass layer that covers the antenna resonating element and the capacitive touch sensor; and
at least one button extending through the glass layer, wherein the metal layer includes an opening that is aligned with the at least one button.

Abstract
An electronic device may be provided with wireless circuitry that includes a radio-frequency transceiver circuit and an antenna. The antenna may be a patch antenna formed from a patch antenna resonating element and an antenna ground. The patch antenna resonating element may be formed from a metal patch on a printed circuit board. The antenna ground may be formed from a metal housing having a planar rear wall that lies in a plane parallel to the metal patch. The radio-frequency transceiver circuit may be coupled to the metal patch through traces on the printed circuit and may be coupled to rear wall of the housing through a screw and a screw boss in the housing. Buttons and other electrical components may be mounted on the printed circuit board and may be coupled to control circuitry on the printed circuit board through the metal patch.
