摘要：Various embodiments of an antenna device for a wireless terminal are disclosed.The antenna device includes a radiator configured to be extracted from/retracted intothe 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 theradiator. The radiator may be configured as a helical coil or at least one meanderingprinted pattern so as to reduce its overall length while maintaining a desired electricallength. In embodiments, the antenna device is useful for UHF/VHF frequency bands.Multi-band configurations are disclosed. In one embodiment, a stainless steel tubemember substantially surrounds a helical coil, and the tube member operates at a lowerfrequency band than the helical coil.
