Embodiment Construction

[0023] electronic equipment (such as figure 1 The electronic device 10) may be provided with a wireless communication circuit. The wireless communication circuitry is operable to support wireless communication in multiple wireless communication frequency bands. The communication frequency bands handled by the wireless communication circuitry may include satellite navigation system communication frequency bands, cellular telephone communication frequency bands, wireless local area network communication frequency bands, near field communication frequency bands, ultra wideband communication frequency bands, or other wireless communication frequency bands.

[0024] Wireless communication circuitry may include one or more antennas. Antennas may include patch antennas, loop antennas, inverted-F antennas, strip antennas, planar inverted-F antennas, slot antennas, hybrid antennas including more than one type of antenna structure, or other suitable antennas. The conductive structures...

Abstract

The invention relates to an electronic device having arrival angle detection capabilities. An electronic device may be provided with wireless circuitry that includes first, second, and third antennasused to determine the position and orientation of the electronic device relative to external equipment. The antennas may include patch elements on respective substrates mounted to a flexible printed circuit. Each substrate may include fences of conductive vias that are coupled to ground and that laterally surround the corresponding patch element. Control circuitry may identify phase differences between the first and second antennas and between the second and third antennas and may identify an angle of arrival of received ultra-wide band signals using the phase differences. The control circuitry may compare the phase differences to a set of predetermined surfaces of phase differences to identify environmental loading conditions for the antenna. The control circuitry may correct the angle ofarrival using offsets identified based on the environmental loading conditions.

Description

[0001] This patent application claims priority to U.S. Patent Application No. 16 / 035,325, filed July 13, 2018, which is hereby incorporated by reference in its entirety. Background technique [0002] The present disclosure relates generally to electronic devices, and more particularly to electronic devices having wireless communication circuitry. [0003] The electronic device typically includes wireless communication circuitry. For example, cellular telephones, computers, and other devices often include antennas and wireless transceivers to support wireless communications. [0004] Forming electronic device antenna structures with desired properties can be challenging. In some wireless devices, the antenna is bulky. In other devices, the antenna is compact but sensitive to the position of the antenna relative to external objects. If care is not taken, the antenna can become mistuned, can transmit wireless signals with more or less power than desired, or otherwise not perfo...
