Electronic device with tunable hybrid antennas
First Claim
1. An electronic device, comprising:
- a housing having a metal housing wall that forms a ground plane;
a slot in the metal housing wall that forms a slot antenna resonating element for a hybrid antenna;
a planar inverted-F antenna resonating element for the hybrid antenna that indirectly feeds antenna signals for the slot antenna resonating element via near-field electromagnetic coupling; and
first and second tunable components that are configured to tune the hybrid antenna, wherein the planar inverted-F antenna resonating element overlaps the slot across an area, the first and second tunable components extend across the slot at first and second respective locations, and the area is interposed between the first and second locations.

Abstract
An electronic device may have hybrid antennas that include slot antenna resonating elements formed from slots in a ground plane and planar inverted-F antenna resonating elements. The planar inverted-F antenna resonating elements may each have a planar metal member that overlaps one of the slots. The slot of each slot antenna resonating element may divide the ground plane into first and second portions. A return path and feed may be coupled in parallel between the planar metal member and the first portion of the ground plane. Tunable components such as tunable inductors may be used to tune the hybrid antennas. A tunable inductor may bridge the slot in hybrid antenna, may be coupled between the planar metal member of the planar inverted-F antenna resonating element and the ground plane, or multiple tunable inductors may bridge the slot on opposing sides of the planar inverted-F antenna resonating element.
