Abstract: A wireless device has an antenna module, an indicating module, and a control circuit. The antenna module has at least a smart antenna. The indicating module has a plurality of indicating units. The control circuit is coupled to the antenna module and the indicating units for determining at least a parameter between the wireless device and at least a wireless apparatus according to radio signals received from the at least a wireless apparatus via the antenna module, and for controlling operations of the indicating units according to the at least a parameter.

Abstract: A multiband antenna is disclosed, which comprises: a low-band antenna assembly, a mid-band antenna assembly, a high-band antenna assembly and a bottom panel. In an embodiment, the low-band antenna assembly is composed of a first dipole antenna and a second dipole antenna that are arranged intersecting with each other; the mid-band antenna assembly is composed of a plurality of connecting mid-band antennas; the high-band antenna assembly is composed of a plurality of connecting high-band antennas; the bottom panel is provided for the low-band antenna assembly, the mid-band antenna assembly and the high-band antenna assembly to be disposed thereon in a manner that the low-band antenna assembly is disposed on top of the mid-band antenna assembly and the high-band antenna assembly for enabling the multiband antenna to achieve optimal operation performance without causing the three antenna assemblies to interfere with one another.
