    In this paper we show the technique of using a retrodirective array consisting of a cluster of sub-arrays configured for use as sensor for automobile control/telemetry applications. Basic system parameters are defined for millimeter operation. The characteristics of softboard sub-arrays are described. Finally, the performance of an unmodulated retrodirective array is given in order to illustrate t... View full abstract»

    An RF transponder is a system allowing contactless identification or communication in applications ranging from mountain/sea rescue to automatic waste management. Such a system is woken by an interrogating signal and sends back a coded response. A potential application in Intelligent Transport Systems concerns dedicated short-range communications (DSRC), in which information is exchanged between r... View full abstract»

    A variety of antennas have been presented which are suitable for manufacture on glass or on or behind plastic panels. These cover the frequency bands currently required for car antennas. New bands will need to be incorporated to cover UMTS for example and current designs are being expanded. This paper summarises some of the work currently being undertaken at the University of Kent on this subject View full abstract»

    The construction and performance of a novel microstrip-polyrod antenna feed is discussed and briefly compared to alternative microstrip feeds for dielectric lenses. This novel antenna feed, which was developed for a 77 GHz automotive radar system, enables microstrip patch radiators to efficiently illuminate dielectric lenses or reflectors, and may also be applied to microstrip antenna arrays View full abstract»

    Optically transparent antennas have potential applications as receivers/transmitters for wireless automotive applications. They can be incorporated in the car's window or light panels thus preserving car aesthetics. These antennas could also be incorporated in the displays of wireless communications electronic equipment. To fabricate these antennas, an optically transparent conductor is required w... View full abstract»

    Developments in high volume consumer-orientated microwave products have fuelled an intensive search for low-cost, low profile, mass-produced antennas. At lower frequencies in the microwave band (<10 GHz), printed circuit or wire antennas can be used. However, at higher frequencies, the efficiency of printed circuit antennas deteriorates considerably and alternative solutions have to be explored... View full abstract»

  • Simulation of far-field characteristics and measurement techniques for vehicle-mounted antennas

    Numerical models of simple monopoles mounted on vehicles are presented which indicate that the far-field gain and radiation patterns for such systems can differ significantly from that of the ideal antenna. The theoretical results also suggest that very significant antenna separations (>30 m) may be required in order to carry out gain measurements using simple transmission measurements for vehi...
