This research consists on a ground plane modification using slots of a PIFA (Planar Inverted F Antenna) handset antenna with the objective to facilitate the integration of the feeding transmission line which connects the antenna with the RF-module. Through this technique it is possible to obtain a multiband antenna while keeping the same antenna geometry, small volume and simplifying the PCB (Printed Circuit Board) design. Numerical simulation using MoM is used to understand the effect of the slots on the groundplane. Several prototypes have been built to validate the present technique.
