isolated mode antenna technology
This is very cool, and I think SkyCross has a winner on their hands here.

The Challenge
Many next-generation protocols require multiple antennas for diversity or MIMO. The advantage to using multiple antennas in a radio-frequency (RF) system is to achieve higher link gain leading to faster data rates, increased network capacity, and better reliability.
Historically, it has been challenging to arrange multiple antennas so they don’t interfere with each other. An obvious solution for keeping the antennas isolated is to move them farther apart, but this is not practical for small mobile devices. The design is either no longer sleek or the antennas don’t fit at all.
The Solution
iMAT is a revolutionary technology that enables a single antenna structure to behave like multiple antennas through the use of multiple feed points. Each feed accesses the antenna as if it consisted of multiple antennas, each with high isolation, low correlation, and high per-feed antenna efficiency. The resulting improvement in antenna gain and receiver sensitivity significantly enhances device performance and network capacity.
The iMAT Advantage
Superior Performance
iMAT enables device manufacturers to offer a high performance, multiple antenna system in any sleek device. Network operators can offer optimized performance without any infrastructure investment. A greater number of efficient devices on a network improves the capacity and bandwidth of the entire system.
Higher efficiency means a better signal for end users, even when the nearest tower or base unit is far away. This reduces dropped wireless connections and supports fast data transfer for high definition video or music, and more. In addition, efficient devices have longer battery life.
Please see the white paper for performance details.
Endless Applications
iMAT makes diversity or MIMO system possible, even in instances where the industry had long ago decided such implementation was impossible due to space constraints. iMAT supports legacy networks and is essential for next generation protocols such as HSxPA, WiMAX, 802.11x, and LTE that require diversity or MIMO.
Any wireless device including handsets, smartphones, data cards, USB dongles, laptops, personal navigation devices, cameras, gaming devices, and more can now take advantage of advanced antenna techniques for voice, data, location, and video applications while maintaining their sleek designs.
Simple Integration & Cost-Effective Manufacturing
iMAT is a ready-made diversity or MIMO antenna system with performance optimization built in to a very small footprint. The need to configure multiple antennas is eliminated.
A single antenna solution means fewer parts on the BOM. Surface mount technology and common materials translate to cost effective manufacturing.
