Antenna

Provided is an antenna including: an antenna stick; and an antenna hinge pivotably attaching the antenna stick to an electronic device body. The antenna hinge includes: a support plate fixed to and combined with the electronic device body; a first connector connected to the antenna stick and pivotably combined with the support plate; a second connector deviating from a pivot center of the first connector and fixed in respect of the support plate; a third connector moving with the pivot of the first connector; and a spring having an elastic force varying with a distance between the second connector and the third connector. If the first connector pivots until the third connector passes a virtual first straight line connecting the pivot center of the first connector and the second connector, the first connector continuously pivots toward an identical direction due to an elastic restoring force of the spring.
