Summary:
The methods that can control the parameters of the dual band antenna were suggested in this paper. The minimization of the antenna was realized by using a helical structure that has loop antenna composed of via and lines on FR-4(εr = 4.4) PCB. The antenna characteristic was analyzed on parasitic components, the size of dielectric and the permittivity by using the commercial software HFSS 3-D EM simulator. The parameters that can control the active region of antenna were verified. And the principle of increasing bandwidth was verified, too. So the antenna was designed to have an optimal characteristic. At last the antenna based on simulation results has 10mm height, 5.8mm width, and 4mm thickness as internal printed antenna for GSM/DCS cell-phone. Its size was minimized so that it can be mounted inside of dual band cell-phone.
