New Description: [New Technology Field] This creation is about an inverted F antenna, especially a dual-frequency inverted F antenna [Prior Art] ° Due to the use of wireless wave transmission technology using electromagnetic waves, in use If there is no need for wiring materials, the effect of communication with the remote device can be achieved, so that it has the advantage of being easy to move, and the types of products using wireless communication technologies are increasing, such as mobile phones and notebook computers. ❿ These products use electromagnetic waves to transmit signals. This antenna for transmitting and receiving electromagnetic signals becomes a necessary device. At present, the antenna b is divided into an antenna exposed outside the skirt and an antenna built in the device, and the antenna outside the device, in addition to affecting the size and appearance of the product, also has the impact of external force impact and bending, Folding _ shortcomings, _ built-in antenna has become a kind of 2C today's 3C device, in order to achieve a multi-purpose function of the machine, in addition to the wireless communication antenna, it is also equipped with wireless network (10) must) antenna, two-way, trend Small and exquisite _, it also means that the two antennas can be set to 'small size, so that the adjacent antennas will affect each other, and the poorest connection, 4 is the result of reducing the radiation efficiency of the antenna, and the result of the connection is low.
