Antenna related features of a mobile phone or computing device are disclosed. In one embodiment, wireless control and signal are fed separately through difference types of flexes to optimize performance and cost. In one embodiment, active switching and processing of differing conductive trace lengths are performed on an antenna flex so that antenna performance can be optimized for multiple wireless technologies covering a wide range of wavelengths. In one embodiment, a cantilever arm affixed to a ground screw can provide double grounding in a region with no available screw points due to high z constraint. In one embodiment, a device can provide double feed for antenna through a single screw. In one embodiment, a short pin can be configured to support thinner metal. In one embodiment, a “vibrator bracket/LDS short pin” structure can be used to share a common screw point.
