Spiral & Sinuous Antennas
Wideband. Compact. Polarisation-Flexible.
AntennaTec’s spiral and sinuous antennas are developed for applications requiring wideband operation, compact directional RF performance, and flexible polarisation capability. Spiral antennas are well suited to circularly polarised operation, while sinuous antennas support wideband dual-polarised configurations for receiving and analysing signals with different polarisation states.
This antenna range is suitable for EW, SIGINT, ESM, RWR, direction finding, spectrum monitoring, reflector-feed applications, airborne and ground platforms, low-power jamming systems, and specialist defence and RF monitoring applications.
Available designs can include left-hand and right-hand circular polarisation, dual-linear or dual-circular polarisation, compact cavity-backed structures, radome-enclosed options, and configurations for single-element, array, and platform-mounted use.
Custom spiral and sinuous antennas can be developed to meet specific requirements for frequency range, polarisation sense, beamwidth, connector interface, mechanical size, radome design, and deployment environment.
