Abstract
Various embodiments of an antenna device for a wireless terminal are disclosed. The antenna device includes a radiator configured to be extracted from/retracted into the wireless terminal, a L-C lumped circuit, and a noise removing coil coupled between the radiator and the L-C lumped circuit, to attenuate noise introduced through the radiator. The radiator may be configured as a helical coil or at least one meandering printed pattern so as to reduce its overall length while maintaining a desired electrical length. In embodiments, the antenna device is useful for UHF/VHF frequency bands. Multi-band configurations are disclosed. In one embodiment, a stainless steel tube member substantially surrounds a helical coil, and the tube member operates at a lower frequency band than the helical coil.
