A Guided Soft Target (GST) system and method provides a versatile test system and methodology for the evaluation of various crash avoidance technologies. This system and method can be used to replicate the pre-crash motions of the CP in a wide variety of crash scenarios while minimizing physical risk, all while consistently providing radar and other sensor signatures substantially identical to that of the item being simulated. The GST system in various example embodiments may comprise a soft target vehicle or pedestrian form removably attached to a programmable, autonomously guided, self-propelled Dynamic Motion Element (DME), which may be operated in connection with a wireless computer network operating on a plurality of complimentary communication networks. Specific DME geometries are provided to minimize ride disturbance and observability by radar and other sensors. Computer controlled DME braking systems are disclosed as well as break-away and retractable antenna systems.

Embodiments of wireless antenna array systems to achieve three-dimensional beam coverage are described herein. Disclosed is an integrated multiple phased antenna array on a flexible substrate with one RFIC. In this way the module can be molded onto the contour of a platform such as a notebook or a hub of the personal area network or local area network. The multiple phased array can be 3D bent in a compact size to fit into thin mobile platforms. Different array antennas or antennas radiate in different spherical directions with beam scanning capabilities while driven simultaneously by one RFIC chip.

An RFID tag includes a base having at least one fold formed therein. An integrated circuit is formed on the base. At least one antenna segment extends from the integrated circuit and crosses the fold. When the fold is creased, a portion of the antenna segment on one side of the fold is aligned to be orthogonal to a portion of the antenna segment on the other side of the fold.
