Multi-octave spiral antenna covers 1 to 18 GHz
At a diameter of 78 mm, the QSP-RC-1-18-S-SG-R antenna provides excellent return loss, gain and axial ratio over the full 1 to 18 GHz operational band and is ideal for satisfying challenging applications which includes ELINT and COMINT systems, radar warning receivers systems, and spectrum management antenna arrays.
Based on an SMA connector, the antenna handles 2-W power (c.w.) with a gain of 0 to 7 dBiC. Tyipical VSWR is <2.5:1. Maximum VSWR is 3.2:1. The antenna’s 3-dB beamwidth is 20 to 112 degrees, while the 10 dB beamwidth is 111 to 181 degrees.
Robert Lowther Steatite Q-par’s sales and marketing manager comments, “The company excels in the research, design and manufacture of a wide range of multi-octave antennas and subsystems typically operating from 100 MHz up to 500 GHz; the new 1-18 GHz antenna is a welcome competitive addition to Steatite’s extensive planar antennas offering which includes a COTS family of wideband sinuous and spiral microwave antenna products covering 0.5 to 42 GHz bandwidth."
