PURPOSE: A helix antenna for a cellular phone is provided to reduce an electromagnetic wave energy absorbed to the human body by installing two helix antennas on the upper or lower portion of the cellular phone with a predetermined separation. CONSTITUTION: An equal power applying unit(110) includes a divider(112), a transmission line(114), and a helix coupling unit(113). The divider(112) uniformly divides an electric power signal applied from a feeding point(121) to two directions. The transmission line(114) is branched two directions from the divider(112) and transmits the electric power of the divider(112). The helix coupling units(113) are formed on respective ends of the transmission line(114) and are coupled to a helix antenna to apply the electric power transmitted through the transmission line(114) to the helix antenna.
