Antenna improves factory-built M2M equipment

Quarterwave has released the Theta E1 2.4GHz antenna for machine-to-machine applications.

Launched to provide improvements to current signal levels achieved by factory-built embedded 2.4GHz equipment using Bluetooth, Wifi and Zigbee, the antenna has been tested in the field and is claimed to provide up to 22% stronger signal levels resulting in faster data rates and better transfer while roaming between networks.

Measuring 38 by 6 by 4mm, it is designed for internal use and is supplied with adhesive allowing fixing to the inside of enclosures – negating the need for a groundplane.

Fed with co-axial cable with either Ipex, UFL or GSC connectors, it provides 2dB isotropic gain via its quarter wave dipole design and is suitable for cable runs in embedded equipment of up to 900mm.

Designed to be adhesive mounted inside wireless M2M or telemetry equipment, the antenna operates on a vertical polarisation.

“Theta E1 enables systems integrators modifying or designing telemetry equipment to optimise the antenna performance in their 2.4GHz design,” said Graham Merry of Quarterwave.

“Theta E1 has been carefully designed as a plug and play solution to existing 2.4GHz modules with a suitable connector to provide a longer working range without the need for additional matching circuitry.”

Based in Hampshire, UK, Quarterwave oversees the production via factories in the Far East prior to final inspection and test in the UK before shipment.
