Summary:
A PCB antenna structure modified from F antenna with different resonating frequency loads were used to create the dual band and wide band antennas. The method of improving the dual band bandwidth has been elaborated. By adding numbers of resonating loads of different branch length, the wide bandwidth was achieved. A structure with loads concentred around two different frequencies was simulated and 3GHz and 5.2GHz dual bands antenna was achieved. Another wide band structure with different loads has been simulated and results has shown 4.09 GHz bandwidth at SWR=4 centred around 4.5GHz (or 90% bandwidth) was achieved. The principle shown here can be applied to different applications by adjusting the matching tapping point, matching loop size, number of the arm loads and their length or resonating points.
