Printed Inverted-F Monopole Antenna for Internal Multi-Band Mobile Phone Antenna

This study applied planar inverted-F monopole antenna to design the 7-frequency mobile antennas with the characteristics of imperceptibility, miniaturized simple production, and low cost. The entire antenna contained the sizes of the ground plane 95 ? 45 ? 0.8 mm3 and the radiator 22.5 ? 45 mm2. The simulation results show the five frequency bands to cover from GSM-850 (824-894MHz), GSM-900 (880-960MHz), DCS-1800 (1710-1880MHz), PCS-1900 (1850-1990MHz), UMTS (1920-2170 MHz), GPS (1575.42-5MHz), to IEEE 802.11b (2400- 2484MHz). With planar inverted-F monopole antenna, a gap between the fed and the ground path was added and the ground path was extended to excite the low-frequency resonant frequencies as well as combine with multi-path resonant frequencies to achieve multi-frequency resonances.
