Abstract
A novel microstrip-fed folded planar monopole handset antenna is proposed.The effect of the structural parameters on the impedance and radiation characteristics of the antenna is analyzed by using FD TD method.The results of FD TD are essentially agreement with experimental results.The proposed antenna has properties of simple structure,broad-band,easier to feed,and easier to integrate.This novel folded planar monopole handset antenna provides a new choice for the third generation mobile communication system.
