Internal triple-band folded planar antenna design for third generation mobile handsets

  A novel internal triple-band folded planar antenna for mobile handsets is introduced, formed by modifying the geometry of a rectangular patch antenna to include a shorting pin, folded sides, a shorted microstrip stub and a notch. The size of the antenna is successfully reduced to a volume of 34 x 34 x 7 mm³. The antenna is mounted on a finite ground plane of 50 x 100 mm². The impedance bandwidth achieved was 29.7% (equivalent to return loss 210 dB); this covers the DCS1800, PCS1900 and UMTS 2000 bands. The characteristics of the proposed antenna, including impedance bandwidth and far field radiation patterns are discussed theoretically and experimentally; the simulated and measured results show good agreement. The tuning effects of the geometry parameters on impedance matching of the proposed antenna are also investigated.
