Abstract :
A dual band PIFA (planar inverted "F" antenna) is designed for the 800 MHz band (824-894 MHz) and 1900 MHz band (1850-1990 MHz) that are the current US carrier frequency bands for mobile service. The PIFA has a J-shaped slot on a fixed substrate. The ground plane size has very small variation. The substrate is 10 mm thick with a dielectric constant of 2.25. The ground plane area is 3 times the area of the PIFA. A coaxial feed is used in the numerical simulation (Ansoft HFSS). Bandwidth enhancement for both bands is investigated.
