摘要：Disclosed is a portable communication terminal usable at multiple frequencieswhile being capable of achieving a reduction in specific absorption rate (SAR). The
terminal includes two dipole antennas mounted on an antenna printed circuit board (PCB)mounted to a PCB of the terminal and respectively adapted to operate at usable
frequencies fand fA coaxial cable is connected at its end to the dipole antennas, and acylindrical bazooka type balun (bazooka) for multiple frequencies is fitted around theend of the coaxial cable. The bazooka includes a first dielectric cylinder, a second
dielectric cylinder, and a conductor cylinder. The dielectric cylinders are coaxially fitted inthe dielectric cylinder. The dielectric cylinders are used for the frequencies fand fwhilehaving electrical lengths corresponding to the frequencies fand frespectively.
