Display Frame Antennas

This creation relates to an antenna, and more particularly to a metal frame antenna that secures an antenna to a display panel to form a display panel.

Under the continuous advancement of electronic technology, many electronic communication devices support 3G, wireless local area network (WLAN), global interoperability microwave access (Wimax), Bluetooth and other functions, allowing users to communicate in different frequency bands. In the coexistence of a variety of wireless communication standards, a multi-frequency (wideband) antenna has been developed for installation in an electronic communication device to accommodate signal transmission and reception in different frequency bands under various transmission standards.

Conventional multi-frequency antennas are used to hide the frame of the housing of a liquid crystal display mounted on a notebook computer, such as the national patent publications No. I370585 and I369024. After the multi-frequency antenna is installed, a transmission line is connected to the signal feeding board to the circuit board of the host, and the signal received by the multi-frequency antenna is transmitted to the circuit board through the transmission line, and the board is processed. The wireless signal to be transmitted is also transmitted to the multi-frequency antenna, and the multi-frequency antenna transmits the signal.

Since the multi-frequency antenna is not suitable for a plurality of frequency bands, and the length cannot be too long, usually the radiator of the multi-frequency antenna is shaped like a meandering, so that the volume of the multi-frequency antenna becomes large, resulting in the installation of the multi-frequency antenna.
