Electronic Apparatus with an Antenna

Abstract

An electronic apparatus with an antenna, an anti-jamming system and a method are disclosed. The electronic apparatus comprises a casing and the antenna. The antenna is composed of a patterned metal thin film and a carrier and provided for processing a wireless signal. The casing and the antenna are made by injection molding. When the electronic apparatus has a display device, the anti-jamming system can modulate a clock signal generated by the display device to prevent the multiplication of clock signal from interfering with signals within an operating band of the antenna.

Problems solved by technology

However, the use of an external antenna 15 not only bends or breaks the antenna easily due to collisions, but also causes inconvenience for users to carry and use the antenna.

If the antenna is installed near a display device, the clock multiplication of the display device will interfere with signals within the operating band of the antenna, and thus lowering the wireless communication performance.

The band used for one kind of wireless communication module is different from the other, and the chance of having an interfered band is increased drastically, and the traditional hardware circuit design is no longer sufficient for preventing interferences.
