%X The development of dual-band dual-mode D-AMPS/AMPS mobile handsets and radio stations has added pressure on GSM service providers to follow similar technology breakthroughs as a first step towards UMTS/FPLMTS. A frequency agile device accommodating both GSM standard frequency bands would serve more than 25 million GSM subscribers, with expectations as high as 100 millions subscribers by the year 2000. The complexity of the spectrum sharing between the two technologies and service generations may be alleviated by all terminal, system and network technologies. Several attempts to accomplish dual-band GSM/DCS 1800 operation on a single handset employing dual-band antenna concepts are introduced, and novel printed antenna elements developed at the Universidad Politécnica de Valencia are described.
