ABSTRACT: By placing a rectangular spiral conducting strip on the
top, bottom, and two side surfaces of a rectangular plastic chip of dimensions
5  10  16 mm3, a novel plastic chip antenna capable of
GSM/DCS dual-band operations in mobile phones is presented. The
plastic chip antenna has the attractive feature of surface mountable and
generates a lower mode for GSM (890–960 MHz) operation and an upper
mode for DCS (1710–1880 MHz) operation. Good antenna performances
are also observed.
