Abstract: A bent and twisted mobile phone support, a bendable part of the mobile phone support being made according to the bendability of some articles, has three or more supporting legs, the spacing between the supporting legs of the support can be adjusted by bending the supporting legs; and has two or more support-stop hooks, extending or protruding forward from a planar structure. Because a deformation part twisted or rotated is distributed on a relatively long connecting arm or supporting leg or twisting rod and is not easy to break by repeated bending and twisting, the support-stop hooks do not need to be bent again after being extended by the twisting or rotating of the supporting legs or connecting arms.

Abstract: An apparatus for reducing interference in an antenna from a radio wave is provided. A method for blocking an electromagnetic wave signal port is used. A WiFi antenna is enclosed by using an electromagnetic wave blocking material (such as an aluminum metal mesh) to form an enclosure surrounding the WiFi antenna. The enclosure is provided with one or more electromagnetic wave signal ports, to form an electromagnetic wave selection enclosure (wave selection enclosure). When a wavelength satisfies a requirement, an electromagnetic wave having a signal with sufficient strength, or a signal in an appropriate direction with insufficient strength (for example, entering the signal port in a route closer to a linear route) is allowed to enter the enclosure and communicate with the antenna, reducing or eliminating mainly interference in the antenna in the enclosure from another co-frequency electromagnetic wave outside the enclosure.
