Q-par Angus Adds Line Of Sinuous Antennas

Q-par Angus has designed and developed a line of wideband sinuous antennas that can accommodate linear, dual-linear, circular, or dual-circular polarization schemes in frequency bands of 0.2 to 2.0 GHz, 0.7 to 4.0 GHz, and 2.0 to 18.0 GHz. As an example, model QSPDP0.2-2S is an ultrawideband (UWB) linear sinuous antenna designed for use from 0.2 to 2.0 GHz. With good cross-polar performance and excellent isolation between ports, the antenna exhibits negligible polarization drift. Its radiation patterns are consistent and reliable, with phase-matched output ports that support circularly polarized operation if required.
