A ballistic resistant body covering for protecting the torso, groin and neck area from ballistic missiles. The ceramic chip antenna according to the present invention comprises a main body, first and second helical conductors, and a single power supply section for supplying power to the first and second helical conductors. Therefore, the structure aforesaid not only achieves the positioning purpose of being damage-free, but also is cost-effective in having a minimum of elements and manufacture processes. The predefined core region may comprise one or more metal layers defining a plurality of power regions formed according to a custom design created after the base layer is fabricated. The driving controller controls the driver by a sequence of pulse signals so as to position the shading member at the shading position for a shading-interval in the one-frame reading interval, and so as to position the shading member at the non-shading position for a remaining reading-interval.
