SUMMARY<br />
Q-PAR ANGUS RELEASES COMPACT<br />
<strong>0.5</strong> - <strong>22</strong> <strong>GHz</strong> SPIRAL ANTENNA<br />
Q-<strong>par</strong> Angus Limited, a microwave antenna and development company based in Leominster,<br />
UK, is pleased to announce the launch of a new “base-line” compact ultra-wideband <strong>0.5</strong> -<strong>22</strong><br />
<strong>GHz</strong> spiral antenna intended for UWB communications, feeds, radio surveillance and direction<br />
finding applications. The 152 mm diameter antenna is Circularly Polarised (CP) with bore-sight<br />
axial ratio better than 3 dB above 0.8 <strong>GHz</strong>.<br />
After thorough development and testing, this new antenna is a welcome addition to Q-<strong>par</strong>’s<br />
range of <strong>Spiral</strong> <strong>Antenna</strong>s. These currently provide wideband performance up to 42 <strong>GHz</strong>, with<br />
either left or right hand CP. The new design will allow Q-<strong>par</strong> to quickly modify the antenna to<br />
meet specific customer requirements, resulting in reduced development lead-times. <strong>Spiral</strong><br />
antennas are used in many applications because of their low cost and size. They are often used<br />
in EW applications such as Radar Warning Receiver (RWR) systems and as Threat Warning<br />
<strong>Antenna</strong>s in threat warning receivers.<br />
Robert Lowther, Q-<strong>par</strong> Angus Sales and Marketing Manager says, “We believe we have<br />
developed an excellent ultra wideband spiral antenna that reinforces our position as a leading,<br />
innovative microwave antenna company.”<br />
