Electronic device with fingerprint sensor and tunable hybrid antenna
First Claim
1. An electronic device, comprising:
- a housing having peripheral conductive structures;
a hybrid inverted-F slot antenna, wherein the hybrid inverted-F slot antenna has an inverted-F antenna portion formed from an inverted-F antenna resonating element and an antenna ground, the inverted-F antenna resonating element is formed from the peripheral conductive structures, the hybrid inverted-F slot antenna has a slot antenna portion formed from an opening between the inverted-F antenna resonating element and the antenna ground, and the antenna ground has an extended portion adjacent to the slot;
an antenna feed that feeds both the inverted-F antenna portion and the slot antenna portion; and
a fingerprint sensor overlapping the extended portion of the antenna ground.

Abstract
An electronic device may have wireless circuitry and components such as sensors. The electronic device may have a metal housing having first and second planar rear wall portions separated by a gap. Conductive structures may bridge the gap to electrically couple the first and second rear wall portions. The wireless circuitry may include a hybrid slot inverted-F antenna. The antenna may have an inverted-F antenna resonating element formed from peripheral housing structures that are separated from the second rear wall portion by an opening. The opening may form a C-shaped slot antenna resonating element for the antenna. The sensors may include a fingerprint sensor. The fingerprint sensor may be coupled to a button member in a button. The fingerprint sensor and other portions of the button may overlap the second planar rear wall portion to minimize interference with antenna operation.
