Abstract

The invention is entitled "Electronic Devices with Shared Antenna Structure and Separate Return Paths". Antenna structures at a given end of an electronic device may include antenna structures that are shared between multiple antennas. The device may include an antenna having an inverted-F antenna resonating element formed from a portion of a surrounding conductive electronic device housing structure, and the device may have an antenna ground separated from the antenna resonating element by a gap. A short path can bridge the gap. The short circuit path may be a split return path coupled between a first point on the inverted-F antenna resonating element arm and second and third points on the antenna ground. The electronic device may include an additional antenna including an antenna ground and metal traces forming the arms of the antenna resonating element. The antenna resonating element arm of the additional antenna may be parasitically coupled to the inverted-F antenna resonating element and part of the split return path.

Description

[0001] This application claims priority to US Patent Application No. 15 / 700,618 in September 11th, 2017 filed the patent application is hereby incorporated by reference herein. Technical field [0002] The present invention generally relates to electronic devices and, more particularly, to an electronic device with wireless communications circuitry. Background technique [0003] The electronic device typically includes a wireless communication circuit. For example, cellular phones, computers and other equipment typically includes an antenna and supporting wireless communications for a wireless transceiver. [0004] Forming an electronic device antenna structure having desired properties can be challenging. In some wireless devices, the antenna is bulky. In other devices, the antenna is compact, but for the antenna with respect to the position of the external object are sensitive. If not careful, the antenna can be changed disorders, available power greater or less than the desir...
