Abstract: A dual-band antenna for mobile communication unit is provided with a support made of insulating materials, a first and a second helical conductors, and a coaxial feeder connected to an end of each of the helical conductors. The first and the second helical conductors are wound on the support to be separated from each other and have a different resonance frequency, respectively. When a voltage is applied to the first and the second helical conductors through the coaxial feeder, the antenna operates in the optimum performance at two frequency bands. As a result, the unit can use a desired different mobile telecommunication service without changing it. Further, the inventive antenna is designed to be small in size to thereby allow it to be adapted on the mobile telecommunication unit.
