A design of the multi-band chip antenna using meander line PIFA structure for mobile phone handset

The paper introduces mobile handset multi-band chip antenna based on meander line PIFA structure. The proposed antenna uses an FR-4 substrate and demonstrated the ability to adjust characteristic impedance by adding parasite patch to ground and by coupling with base radiator. The fabricated antenna with the dimension of 4 mm height, 6 mm width and 28 mm length. The ground plane a dimension of 90 times 40 [mm], designed by a commercial software CST simulator. The experimental results show that the impedance bandwidth for (VSWRO) is 90(875 ~ 965) MHz in GSM 900 band operation and 380(1.670 ~ 2,050) MHz in DCS, PCS band operation. The maximum gains of antenna are 0.25 dBi, 2.21 dBi and 2.71 dBi at resonance frequencies and it has omni-directional pattern practically.
