In this paper, the electric field distribution and directivity on human head caused by portable phone is analyzed. An analysis model is composed of a human head model and the antenna mounted on the same ground plane as portable telephone size. The QMSA to load a capacitor without limitation of the electric force is used In the computational model to apply to the antenna mounted on portable phone. This antenna is designed to operate in the near of frequency 2.0㎓, is observed the radiation characteristics of the antenna and their variations as a function of distance from the human head.
