2 - 18 GHz Dual Polarised Sinuous Antennas
Filed under:
Datasheet
The QSPDCP2-18SRA ultra wide band circularly dual polarised sinuous antenna is manufactured from aluminium and engineering composites. Its compact size, minimal beam squint and circular dual polar capability make it an attractive candidate for many air-borne and precision ground-based applications.
Model Number QSPDCP2-18SRA
We are delighted to announce our full Technical Production Specification for this part. Details are below.
The 2 - 18 GHz Sinuous Antenna is a particularly versatile antenna for many applications. Radiation pattern beamwidths are closely matched between E & H planes and have remarkable stability versus frequency. This, and the small variation of phase centre, also make it an attractive candidate for feeds in reflector dishes.
Features
-
Suitable for use in electronic surveillance, ESM, threat warning systems, direction finding and reflector feeds requiring little phase centre variation with frequency
-
Gain -6 to +1 dBiL across the band
-
Low weight and small size enhance usability
- A lensed radome is also included
- A test report including gain against frequency is provided with each antenna
