Abstract
An antenna for a mobile communication terminal in which part of an antenna rod is slidably mounted into an assist antenna rod such that the antenna may be selectively extended in one or two stages. A connecting portion between the antenna rod and the assist antenna rod is rolled so that the antenna rod is prevented from being easily escaped from the assist antenna rod when the antenna is extended in two-stage. Thus, an enhanced communication quality may be obtained by extending the antenna length even when the mobile communication device is slimmed and an optimized length of the antenna is not secured.
Claims3
An antenna for a mobile communication terminal comprising a hollow support rod mounted in a mobile communication terminal, an antenna rod slidably mounted in the hollow rod, an assist antenna rod slidably mounted into a portion of the antenna rod, and an antenna fixing unit for defining movement range of the antenna rod and fixing the same, said antenna further comprising:
- a keeper arranged at an outer surface of said antenna rod which is to be secured to said assist antenna rod for catching the antenna when extended in two-stage;
- and
- said assist antenna rod which is connected to said antenna rod has an inner circumference part of which is rolled toward the inner space of said assist antenna rod such that said antenna rod may not be escaped from said assist antenna rod.
