“…THE DUAL-BAND DUAL-MODE ANTENNA SCHEME The mobile handset requirements of small size, light weight, thin profile and low cost bring up printed antennas as an interesting altemative for mobile terminals. Studies on some of these printed elements include antennas like the PIFA, BIFA, RCDLA, or BMMDPA among others (4)- (5). Several printed dual-band antennas schemes for dual-mode GSM/DCS 1800 handsets have been developed at the Universidad Polit&nica de Valencia.…”

The rapid increase in the use of dual-band dual-mode handsets worldwide has aroused the needfor more compact terminals. Although the monopole has demonstrated to endorse large specific absorption rate (SAR) values, manufacturers still rely on it as the handset antenna for new dual-mode terminals, with some commercial devices even exhibiting a dual-monopole configuration. This extension to higherfrequencies for the new, generation ofcellular systems can lead to increased electromagnetic absorption in the human body, making the new mobile communications equipment an issue ofpublic health concern. In this paper, several attempts to accomplish dual-band GSA/DCS 1800 operation on a single terminal are described While keeping similar radiation characteristics, a tremendous SAR reduction has been obtained by using printed bow-tie antennas compared to the ½-wavelength monopole.

The recent developments of dual-band dual-mode D-AMPSIAMPS mobile handsets and radiostations has added pressure on GSM service providers to follow similar technology breakthroughs as a first step towards UMTSRPLMTS. A frequency agile device accommodating bothL 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. 111 this paper, 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 Politicnica de Valencia are described.
