Abstract
In this paper, we design the dual frequency antenna that could easily determine two operation frequencies by its inverted-F antenna structure and spur line length. The spur line is applied to the inverted-F antenna, in order to dual operation characteristics in PCS and cellular frequencies. It has designed by using the IE3D commercial software based on the moment method. As the designed antenna is fabricated and measured, you can see the results such as the return loss, the input impedance, the radiation patterns, and the gain. The size of this antenna is 40 mm$\times$14 mm$\times$9.4 mm, it is compact enough to use as an intenna. Also, This antenna can be used with cellular and PCS phone of domestic market.
