Claim:
1. A portable information handling system comprising: a housing; a processor disposed in the housing and operable to execute instructions to process information; a memory disposed in the housing and interfaced with the processor, the memory operable to store the information; a display integrated in the housing and interfaced with the processor and memory, the display operable to present the information as visual images and to accept touches as inputs; a transceiver interfaced with processor and operable to communicate information with wireless signals; an antenna interfaced with the transceiver to transmit and receive the wireless signals; and an antenna controller interfaced with the display and the transceiver, the antenna controller operable to alter performance settings of the antenna based upon areas of the display that sense touches, the performance settings comprising antenna impedance and the antenna controller altering antenna impedance based upon touch proximity and size relative to a position of the antenna, the antenna controller imposing a predetermined latency before altering the antenna impedance, the latency preventing impedance changes for transient touch detection.
