Publication number: 20200388913Abstract: An apparatus for a wireless device includes a radio front end module (RFEM) configured to generate radio frequency (RF) signals. The apparatus further includes a multi-layer display, including a liquid crystal display (LCD) layer, a touch panel layer, and a cover glass layer. The apparatus further includes an antenna configured to transmit the RF signals. The antenna includes a primary coupling feeding structure, configured to receive the RF signals from the radio front end module via a feed line. The antenna also includes a generating structure configured to radiate the RF signals. The generating structure is alternating current (AC) operably coupled to the primary coupling feeding structure and is within a visible portion of the multi-layer display. The primary coupling feeding structure can include a non-transparent material and is disposed in a non-visible area of the cover glass layer.Type: ApplicationFiled: November 19, 2018Publication date: December 10, 2020Inventors: Mei Chai, Bryce D.
