A Multiband PIFA with a Slot on the Ground Plane for Wireless Applications
In this paper, the authors present a new configuration of Planar Inverted-F Antenna (PIFA) for mobile communication devices. Simulated results demonstrate that the new configuration covers DCS/PCS/UMTS/WiBro/Bluetooth/S-DMB/WiMax/WLAN frequency bands. Simulated return loss of the proposed antenna is acceptable over all the mentioned frequency bands. Overall size of the proposed design is 40 mm x 21 mm x 5 mm on a 100-mm-long chassis. In designing the PIFA, they propose a slot on the ground plane for increasing bandwidth at about 2 GHz that around of this frequency, there are many wireless communication bands. The antenna is simply printed on an inexpensive FR4 of 0.8-mm thickness and dielectric constant of 4.4. Structural dimensions of the proposed antenna are optimized by using HFSS.
