Electronic Device Antenna With Embedded Parasitic Arm

摘要

An electronic device may have wireless circuitry with antennas. An antenna resonating element arm for an antenna may be formed from peripheral conductive structures running along the edges of a device housing. The peripheral conductive structures may form housing sidewalls. A slot may be machined into a metal housing that separates the housing sidewalls from a planar rear housing portion that forms a ground for an antenna. The slot may be filled with plastic filler. A parasitic antenna resonating element arm that supports an antenna resonance at high band frequencies may be embedded within the plastic filler. The parasitic antenna resonating element may be formed from a portion of the planar rear housing portion.

1. An electronic device, comprising:
a housing having peripheral conductive structures; and an antenna that has at least one resonating element arm formed from the peripheral conductive structures, that has an antenna ground that is separated from the antenna resonating element arm by a slot that runs along at least one edge of the housing, and that has a parasitic antenna resonating element in the slot that is formed from a portion of the housing.
