Wireless device including a metal frame antenna system based on multiple arms
A metal frame antenna (MFA) system comprises multiple arms developed to cover multiple ranges of frequencies normally required in a wireless device such as a phone. The MFA system comprises a ground plane layer, a first electrical arm including a strip element at an edge of a phone spaced apart from an edge of the ground plane layer, a second electrical arm comprising a strip element and/or an antenna booster, a branching system connecting the first and second arms to a feeding system that is connected to the RF system of the phone.
