In this paper, we present a very simple multi-band technique for a wire inverted-F antenna designed for cellular application inside handset terminals, using multiple branch elements, single feeding port and only one shorting strip to simultaneously obtain good impedance matching at many different frequencies. The results in our investigation show that, the proposed technique is extremely straightforward, and can be simply applied to multi-band design of inverted-F antenna, so that it is possible to control easily and independently both the position and the number of all resonant frequencies.
