Methods, devices, systems, and computer program products are provided for adaptive hover operation of touch instruments, which may increase hover height and improve user experience. Hover range may be adapted, for example, by adapting an antenna configuration during hover. A touch instrument may comprise multiple antennas that may be activated and deactivated, e.g., as a function of proximity Antenna configuration may increment (e.g., increase cumulative antenna size) as hover height increases and decrement (e.g., decrease cumulative antenna size) as hover height decreases. Antennas may be multi-purpose, such as being used to maintain synchronization for extended hover range and for other purposes (e.g., determining hover height, tilt, orientation, grip) and/or features (e.g., providing commands for pop-up menus). Adaptive hover may support (i) maintaining synchronization during use, (ii) faster synchronization when a touch instrument enters or re-enters detectable hover height, (iii) improved palm rejection and (iv) pop up menu presentation.
