Abstract: A smart electric meter is provided. The smart electric meter includes a body, an antenna holder, an antenna structure and a supporting member. The antenna holder is disposed on the body, wherein the antenna holder is annular. The antenna structure is disposed on the antenna holder, wherein the antenna structure is moveable along a circumferential direction of the antenna holder. The supporting member is connected to the antenna structure, wherein the supporting member is moveably disposed on the antenna holder, and the supporting member moves the antenna structure along the circumferential direction of the antenna holder.

Abstract: A smart meter capable of performing wireless transmission is used to show some power information, in which the smart meter includes an inner cylindrical case, a ring layer, an inner-layer antenna, and an outer-layer antenna. The interior of the inner cylindrical case is hollow. The ring layer surrounds the inner cylindrical case. The inner-layer antenna is attached to the ring layer and slides on the ring layer. The outer-layer antenna is also attached to the ring layer and overlaps as well as contacts with the inner-layer antenna. The inner-layer antenna and the outer-layer antenna are driven to adjust a total length of them in order to receive signals of different frequency bands.
