    Abstract: A radio frequency (RF) device includes a display screen and a flexible substrate. The display screen is configured to transmit visible light at a first side of the display screen. The flexible substrate includes a first portion overlapping the first side, and a second portion overlapping an opposite second side of the display screen. The RF device further includes a plurality of antennas disposed over the first portion of the flexible substrate and the first side, and a transmission line disposed on a bent region of the flexible substrate between the first and second portions. The plurality of antennas is configured to transmit/receive RF signals on the first side of the display screen. The display screen is opaque to the RF signals. The transmission line is configured to propagate the RF signals between the first portion and the second portion on the opposite second side of the display screen.
