Cheng-Jung Lee, Maha Achour, and Ajay Gummalla Rayspan Corporation, San Diego, CA, USA Cheng@rayspan.com Introduction The use of multiple antennas for diversity, including Multiple Input Multiple Output (MIMO), is one of the most promising wireless technologies for broadband communication applications [1]. The benefits range from improved data throughput, wider network coverage, higher channel capacity and link reliability. However, all wireless devices are becoming smaller as manufacturing technologies for integrated circuits improve over the years. This presents a significant challenge for incorporating multiple antennas in compact consumer devices such as cell phones, wireless adapters and PDAs. In addition to creating a novel a
