Some data indicates that apple has designed a special keyboard keys which contains a built-in conductor area, the wrap-around wire contributes to the design as the antenna, the antenna can also be integrated with the indicators such as "CAPS LOCK" key. This keyboard antenna can be used for Wi-Fi and bluetooth, and it can also be used in other types of communication chains such as 3G and GPS. The wireless antennas will be hidden in some less frequently used keyboard keys.
Apple will hide the wireless communication antennas in several locations in the keyboard of the laptops, and when the user has a communication request, the computer will determine which antenna is in the best signal State, and automatically switch.
Apple's patent does not specify the specific type of the wireless communication, such as whether a Bluetooth or Wi-Fi antenna, or antenna used for mobile communications. The type of signal the antenna take over will depend on the antenna configuration.
According to the statistics from relevant website, this is Apple's fourth patents which relate to the wireless communication function of MacBook in the past year and also the second patent on hiding the antenna.
It is reported that after repeated failure of the product, the design and specific location of the antenna has become an important task for the apple designer. Last summer, iPhone 4 users found that when you touch the antenna position of the phone, the signal will be greatly affected. In the last year, users found that the MacBook notebook will have problems when using Magic Mouse and other external Bluetooth attachments because of the location of the antenna of the notebook.
