Abstract :
The characteristics of a built-in folded dipole antenna (BFDA) for handsets are introduced and analyzed to make it lower profile. In the analysis, the electromagnetic simulator IE3D based on the method of moments (MoM) is used. Both theoretical and experimental analysis of the antenna performance such as input impedance, current distribution and radiation pattern, are shown for both unbalanced and balanced feeds.
