APPARATUS FOR REDUCING INTERFERENCE OF ANTENNA FROM WIRELESS ELECTROMAGNETIC WAVE

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. In the present disclosure, the interference caused to the WiFi router due to the co-frequency or frequency adjacency can be reduced. In the present disclosure, after an actual test, the effect is very good, and an Internet access speed of a device such as a mobile phone through WiFi can obviously become more stable and faster.
