Metamaterial Pioneer Rayspan to Present and Exhibit Its WLAN and WWAN Applications at the third European Conference on Antennas and Propagation (EuCAP 2009)

SAN DIEGO - Rayspan Corporation, the world’s leading innovator of Metamaterial air
interface solutions, is proud to announce that its Chief Technology Officer
Dr. Maha Achour will give a presentation entitled “The Road to 4G through
Metamaterial Air Interface Technology: Long Term Evolution (LTE) and Beyond”
at the third European Conference on Antenna and Propagation (EuCAP 2009). The
company will also exhibit its latest WLAN and WWAN Metamaterial handset
solutions.

Dr. Achour has stated that, “Emerging 4G wireless broadband access
standards will require support of data rates not previously achievable in
compact mobile devices. More specifically, 3GPP Long Term Evolution - LTE -
must enable 100 Mb/sec downlink and 50 Mb/sec uplink peak speeds. This is
accomplished through use of wideband channels at frequencies as low as 700
MHz, advanced modulation techniques, and above all
Multiple-Input-Multiple-Output (MIMO) antenna technology. But until now,
implementing MIMO solutions in the small area and volume available in a
compact mobile device resulted in serious reductions in system throughput and
range.

Only Rayspan’s breakthrough Metamaterial MIMO solutions can achieve full
MIMO performance within the ultra-compact antenna size and close antenna
proximity required for implementation in small mobile wireless devices.
Metamaterial MIMO permits antenna size and antenna spacing to be less than
one fifteenth of a wavelength, and because these antennas are printed
directly on a mobile device PCB they occupy nearly zero volume. Moreover,
they are easily fabricated at extremely low cost, enabling rapid commercially
successful deployment.”

Rayspan’s Metamaterial antenna structures have a unique capability to
concentrate electromagnetic fields and currents very closely to antenna
structures rather than spreading them along antenna grounds, greatly reducing
coupling among antennas. Eliminating coupling among antennas in a MIMO array
achieves full de-correlation of multipath channels and achieves full MIMO
throughput and range.

Metamaterial solutions available from Rayspan today include a broad line
of single and multi-band antennas and arrays together with complementary
directional couplers, power combiners and power splitters. These solutions
address virtually all segments of the billion unit wireless local- and
wide-area network equipment markets, and they can be implemented quickly and
inexpensively by Rayspan’s licensees.
