Direction Finding Antennas and Accuracy Part 3: The Art of designing DF Antennas by Johan Fuhri

In the previous two blog posts we discussed some of the effects that could influence the sensitivity of a DF antenna system.  These were mostly related to the environment, and often manifests in a DF measurement as noise or interference which reduces the ability of the DF system to accurately estimate the angle of arrival….

Direction Finding Antennas and Accuracy Part 2: Characterization of DF antennas

By Johan Fuhri, Product Owner In the previous blog post we considered some of the ways in which we can express the performance of an DF antenna, and we noted that simply stating the ‘accuracy’ of a DF antenna is not quite that simple.  We also noted that there are various algorithms that can be…

Direction Finding Antennas and Accuracy

By Johan Fuhri, Product Owner Part 1: Accuracy and Sensitivity It is sometimes said that: “If you can’t convince them, confuse them!”.  Nowhere is this more apparent than the minefield which is antenna datasheets and brochures. Direction finding antennas are meant to be instrumental in accurately determining the direction of an incoming signal, that much…
