Future iMacs, MacBooks, iPhones and iPod touch might have antennas behind the logo
Antenna technology was a problem area when Apple introduced the iPhone 4 six months ago. Steve Jobs, CEO Apple did clarify the issue pertaining to the new Antennae technology used in iPhone 4. We also got a glimpse of Apple's Antenna Design and Test Labs - http://www.apple.com/antenna/. At these Labs, Apple Engineers are now working on a new Antenna design to place it behind the Apple Logo of portable devices. Patently Apple spotted a patent that describes a filing about Logo Antennas in Apple's portable products.
The Apple iPad has its antenna just behind the logo, which clearly shows what Apple's hardware engineers have been aiming to do. Apple Hardware Engineers are now working to place the Antennas behind the Apple Logo to gain stronger signal without intervening metal or interference from other conductive housing walls. Antenna won't be limited just to Wi-Fi but would cover cellular telephone bands such as GSM 850/900/1800/1900/2100MHz data bands. Apart from the multi-band telecommunications, the antennas would also support Global Positioning System capabilities.
Apple's Patent calls the new antenna technology as Logo Antenna and hardware engineers state that it's possible to cram behind the logos of mobile devices such as iPhone or iPod touch. Even laptops such as MacBooks can have this antenna behind the logo and hence might offer telephony option. In addition to that, these antennas can be placed in desktop machines like iMacs and Mac Minis.
Logo Antennas would be placed Apple products within housing machined from precision unibody aluminum block or other metals. The walls of housing might be used to hold conductive components such as displays. So the conductive antenna cavity might help isolating the Logo Antenna from other circuit inside the housing.
Year after year Apple aims at offering slimmer products and thereby increasing the challenge for hardware engineers to place the antenna in the best location in the product. It would be interesting to see future Apple products carry the Logo Antenna technology.
