Abstract
The planar inverted-F antenna (PIFA) has been popular for mobile communication
applications because of its small form factor and low manufacturing
cost necessary to meet the specifcations of small hand-held devices. A detailed
parametric study of several PIFA designs, including a U-Slot PIFA,
was conducted via computer simulations using a finite element solver (FEM)
software, ANSYS HFSS. The PIFAs were designed to achieve a dual-band
operation in the Industrial, Scientifc and Medical Radio (ISM) bands of 2.45
GHz and 5.8 GHz. The simulation results were confirmed via fabrication and
measurement. The second part of this research is to study various ground
plane modifications to achieve a greater bandwidth at the desired frequencies.
Achieving greater bandwidth will allow for further antenna miniaturization
through height-bandwidth trade-offs.
