Abstract
A capacitively loaded planar inverted-F antenna (PIFA) is proposed and studied, It is found that the capacitive load reduces the resonance l ength of the PIFA from lambda/4 to less than lambda/8. A design with a bandwidth of 178 MHz centered at 1.8 GHz is provided to demonstrate t hat compact antennas for mobile telephone handsets can be constructed using this approach, The finite-difference time-domain (FDTD) method i s used in the study and experimental verification is also provided.
