If the news of Apple's newly-granted patent on a SIM tray wasn't enough to get you all excited this morning, here's some additional patent news that should have bouncing up and down with delight. OK, maybe not, but Apple did secure a second patent today -- Number 8,144,063, which was applied for on March 28, 2011. It's all about "Antenna isolation for portable electronic devices."

The abstract of the patent begins with "Portable electronic devices are provided with wireless circuitry that includes antennas and antenna isolation elements. The antennas may include antennas that have multiple arms and that are configured to handle communications in multiple frequency bands." In other words, this patent covers those antennae that are used on iPads and iPhones to handle Wi-Fi, Bluetooth, and a variety of cellular frequencies.

That diagram at the top of this post is representative of the type of things discussed in the patent. In case you're wondering what that is, it's a "perspective view of a portable electronic device antenna structure with antennas and antenna isolation elements in which the antenna isolation elements each have a bent portion that runs perpendicular to the longitudinal axis of the antennas in accordance with an embodiment of the present invention." So there.
