Description

technical field

[0001] The present invention relates to an antenna structure, and in particular to a multi-frequency antenna structure. Background technique

[0002] Connection and communication between various wireless networks or system devices such as wireless personal area network (WPAN), wireless local area network (WLAN), and wireless wide area network (WWAN), All can be realized by the antenna device installed therein.

[0003] Generally speaking, the antennas of various wireless devices can be designed as external connections or built into the devices. For example, some notebook computers will set the external antenna on the top of the screen, or design the external antenna on the PCMCIA card, and communicate with the computer through this interface. Such an external antenna design may require high cost and be easily damaged due to being exposed to the external environment. In another design, the antenna is directly built into the notebook computer.
