RAYSPAN Corporation today
announced the launch of a new standalone metamaterial balanced antenna
(MTM-B(TM)), offering an integrated solution for ultra-high performance
WiFi access points and routers. MTM-B(TM) is designed to meet the
requirements for single band 2.4 or 5.0GHz designs as well as dual band
2.4/5.0GHz devices, in a small form factor of 15mm X 14mm, which is 80%
smaller than typical dipole solutions offered today.
"Rayspan is pleased to be able to offer our customers the
smallest balanced antenna form-factor available for single and
dual-band WiFi devices," stated Gregory Poilasne, Vice President of
Business Development for Rayspan. "The MTM-BTM will enable WiFi routers
and access points with internal antennas, completely replacing
full-sized dipole antennas and allowing for a more compact design
without sacrificing performance."
Balanced antennas offer multiple advantages to WiFi product
designers. They can be positioned in close proximity to a ground plane
without impact on the antenna characteristics. Balanced antennas also
offer a higher immunity to noise and therefore improved sensitivity and
higher long-range through-put performance. The metamaterial concept
used to design these antennas allows for up to 5x size reduction
without performance trade-offs, as well as a strong immunity to changes
in surroundings. Stronger polarization along the length of the MTM-B(TM)
antenna is beneficial for WiFi products incorporating chipsets that
take advantage of polarization in order to improve through-put and
range. This results in WiFi routers and access points with better
can be printed directly on the PCB, retrofitted inside existing
products or integrated inside new devices. As the WiFi industry
migrates from 2.4GHz only devices to 2.4/5GHz functionality, the dual
band capability of RAYSPAN’s MTM-B(TM) antennas meets the requirements
of 2×2 and 3×3 dual concurrent chipsets where a high Quality Of Service
(QOS) is required for applications such as high definition video
transmission inside the house for entertainment or gaming.
Product Release Schedule
RAYSPAN balanced antennas are sampling to selected customers today,
and will be in volume production during Q1 2010. The first customer to
deliver products incorporating the MTM-B(TM) will be NETGEAR.
"NETGEAR is excited to be working with Rayspan on WiFi
devices using the MTM-BTM technology," said Som Pal Choudhury, Senior
Product Line Manager at NETGEAR. "We will be able to bring innovative
new devices to market that will extend our products’ range and improve
our customers’ overall in-home wireless experience."
