Abstract

A support stand suitable for a hand-held device is provided. The support stand has a first support member and a second support member. The second support member slidably fits the first support member and could be temporarily fixed at different positions on the first support member to adjust the length of the support stand. The hand-held device has a display screen and an antenna. Because the length of the support stand is variable, the hand-held device could be laid on the table by various inclination angles. Besides, the projections of the support stand and the antenna on the display screen are not overlapped, and the influence of the support stand made of metal on the signal of the antenna would be lowered.
