Slim NFC antenna integration into metal-covered tablet and all-in-one desktop PC

Abstract

This paper reviews the new slim NFC antenna integration under the bezel for the metal-covered tablet and all-in-one desktop PC. The conventional NFC antenna of the tablet was embedded under the rear cover because the material of the rear cover of the tablet was ABS plastic which allowed NFC magnetic field to radiate through the rear cover. However, the materials of the rear cover of some tablets and all-in-one desktop PCs were metals such as magnesium or aluminum which did not allow NFC magnetic field to radiate through the rear cover. In order to resolve this issue, the slim NFC antenna was developed and integrated under the bezel of the front screen.
