Design and Simulation of Multiband Planar Inverted-F Antenna for Mobile Phone Applications
The proposed multiband planar inverted-F antenna has a very simple structure. The antenna has only one layer so it is easy to fabricate. The size of radiating patch of proposed antenna is 20mm? 25mm, while the size of ground plane is 39mm?39mm and height of antenna is 3mm. Mathematical tools are used to determine the initial dimensions of the patch and RT Duroid has been used as a dielectric material. Slots in radiating patch have been used to introduce multiband operations into the proposed antenna. Slits in the ground plane of the proposed antenna have been employed to enhance the bandwidth and the number of frequency bands.
