Steatite Q-par Antennas, a microwave antenna, subsystem and consultancy company based in Leominster, UK, announces the launch of a new 2 to 24 GHz Dual Linear Sinuous Antenna, at the European Microwave Week 2013 event. The low squint ultra wide bandwidth antenna is suitable for use in the EW and SIGINT market providing intercept opportunities for a wide range of arbitrarily polarised hostile signals.

The QMS00042 antenna simultaneously handles signals of any two orthogonal polarisations, is compact in size, lightweight and rugged in construction and manufactured from aluminium and engineering plastics. It is ideal for Land, Sea and Air applications including ELINT, ESM and radar warning receiver (RWR) systems.

“This new 2-24 GHz antenna extends the Q-par family of sinuous antennas covering a very wide bandwidth for our EW and SIGINT customers. We are pleased to be showcasing Q-par’s wide range of capabilities at our stand A179, where many of our customers will be attending the prestigious European Microwave event,” said Robert Lowther, Sales and Marketing Manager. “Our sinuous antennas continue to meet the growing demands for Q-par’s wide range of antenna products and services in Europe and Asia.”
