Zusammenfassung:	A head-mounted device may have a head-mounted housing. A radar sensor may be mounted in the housing. The head-mounted housing may have rear-facing displays that display images for a user. The images are viewable from eye boxes while the head-mounted device is being worn by the user. A forward-facing camera may capture real-world image content. The rear-facing displays may be used to display captured real-world image content merged with computer-generated image content. The forward-facing camera and the radar sensor may be mounted under inactive display borders of a forward-facing display. The radar sensor may have a horizontal array of patch antenna elements configured to form a phased antenna array. Communications circuitry in the head-mounted device may use the phased antenna array to transmit and receive wireless communications signals.
