Mobile terminal

This invention describes a mobile phone design where a short-range antenna is placed inside the device, specifically under the display screen. It's mounted on the phone's internal frame, positioned between the frame and the display, and designed to send its signal directly towards the screen. The phone also features a metal back cover, and the frame itself can be metal, with an optional shielding layer for the antenna.

Why it matters: The widespread adoption of full-screen designs and metal bodies in mobile devices, especially smartwatches, since 2016 has made antenna integration challenging. This design offers a compact solution for short-range communication under the display, particularly useful for NFC in metal-cased wearables.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedRF engineering, compact antenna, metal housing
