Novelda Announces Nanoscale Sinuous Antennas

October 11, 2011

The high-precision, directional radar technology is a new electromagnetic sensor that offers enhanced visibility in human vital-sign, personal security, environmental, and industrial automation applications.


OSLO, Norway /PRNewswire/ -- Novelda AS announced two new antennas for its CMOS Impulse Radar Transceiver Development kits. The antenna design is based on a Sinuous Antenna geometry. The antenna itself consists of two printed circuit boards, spaced by about 15 mm. The upper PCB is the antenna itself; the lower PCB is a balancing network. The antenna has a broad radiation beam of about 70°. This can be lowered by attaching a lens. The lens is built from a plastic material and is mounted with 4 screws onto the antenna. Together with the lens, the antenna will have a –3dB beam-width of about 40°.

The Novelda 6.0 8.5 GHz Sinuous Antenna is specifically designed to work with the NVA6000 radar chip. The highly directional antenna is optimal for radar and ranging applications. A detachable dielectric lens is included to further increase the gain and lower the opening angle, at the cost of a slightly bigger antenna.

The Novelda 3.1 5.6 GHz Sinuous Antenna is specifically designed to work with the NVA6100 radar chip. The highly directional antenna is optimal for radar and ranging applications. A detachable dielectric lens is included to further increase the gain and lower the opening angle.

Novelda's mission is to develop and manufacture impulse radar technology as a new electromagnetic high-precision sensor for human vital sign monitoring, personal security, environmental monitoring, industrial automation and other novel sensor applications.

The Novelda Impulse Radar is a complete CMOS radar transceiver, integrated on a single chip. The high bandwidth of the transmitted pulses offers unique penetration abilities and very high accuracy.

In addition to being an alternative to, or complementary to, existing technologies—such as image, ultrasound, and infrared sensors—it opens up new application areas due to its speed, resolution, and ability to "see through" obstacles. No more lenses need to be cleaned, and thus the cost of ownership can be dramatically reduced in comparison to technologies requiring free visibility. Since the NVA6000-series chips are single chip transceivers, they are very suitable for integration into small and mobile devices.

About Novelda
Novelda AS is a privately held, R&D-driven, fabless semiconductor company, based in Norway, specializing in nanoscale, wireless, low-power technology for ultra-high resolution impulse radar. Novelda was founded in 2004 as a spin-out from the University in Oslo, and there is a strong research and development partnership with the university.
