Abstract

The embodiment of the present invention discloses a protective casing for use with a communication terminal; the communication terminal includes a metal backboard and a metal frame, and a gap is provided between the metal backboard and the metal frame; the metal frame corresponding to the metal gap The area is provided with a first radiation area; the first radiation area can work in the WiFi frequency band to form the first WiFi antenna, or work in the GPS frequency band of the Global Positioning System to form a GPS antenna; the protective shell at least includes: a protective cover and a protective cover installed on the protective cover The metal body on the top; the protective cover is made of an insulating medium; the metal body is coupled or short-circuited with the first WiFi antenna to form a second WiFi antenna. The metal body and the first WiFi antenna in the communication terminal share the second WiFi antenna. The second WiFi antenna introduces a metal body on the basis of the first WiFi antenna, which broadens the working WiFi frequency band or adjusts the impedance of the original WiFi antenna. Better impedance matching is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a protective casing. Background technique [0002] With the development of electronic technology and wireless communication technology, more and more antenna structures are added to communication terminals. For example, a mobile phone serving as a communication terminal may generally be integrated with a mobile data antenna, a Global Position System (Global Position System, GPS) antenna, a WiFi antenna, and the like. The mobile data antenna is generally used for mobile communication in a cellular communication network, and the GPS antenna can be used for positioning using a global positioning system. The WiFi antenna can be used for communication based on WiFi transmission. [0003] However, in order to facilitate the portability of communication terminals, there is an increasingly strong demand for thinner and lighter communication terminals. However, the thinning and thi...
