Abstract
A biaxially rotational structure for a planar antenna comprises a biaxial base having a vertical direction and a horizontal direction, a vertical shaft assembly disposed at the vertical direction of the biaxial base, the vertical shaft assembly has a rotation limiting member; a support frame pivotally mounted on the vertical shaft assembly, the support frame having a stopper extending downwardly in a manner that the rotation limiting member limits the stopper to rotate within one turn with respect to the vertical shaft assembly; a first resilient member disposed between the vertical shaft assembly and the support frame for exerting a pressing force on the support frame; a horizontal shaft assembly disposed at the horizontal direction; and a second resilient member disposed between the horizontal shaft assembly and the biaxial base for exerting a friction force therebetween. Therefore, the biaxially rotational structure of the present invention will prevent the user from unlimitedly rotating the planar antenna,along the directional angle (vertical direction), thereby the cable therein might not be tangled and broken.
