Abstract

An internal WWAN (824~960/1710~2170 MHz) handset antenna suitable to be embedded in a small notch of 35 × 6 mm² in the system ground plane of the handset is presented. The antenna occupies a small volume of 35 × 6 × 3 mm³ or 0.63 cm³ only. To fit in the small notch, a quarter-wavelength gap-coupled loop antenna is applied, which not only can be configured into a compact configuration but also can be in proximity to the surrounding ground plane. With the aid of a matching network, which is comprised of a series chip inductor and a band-stop matching circuit, two wide operating bands to respectively cover the GSM850/900 and GSM1800/1900/UMTS operation are obtained.
