Say there was a large reflective wall blocking 90 degrees of view horizontally and from horizon to 60 degrees vertically. It could be a building or rock face, or a stand of trees.
We already block signals bouncing up from below with the ground plane, but what about signals bouncing from the side? Is there a good way to block one side of a GNSS antenna?
Could they be absorbed, or deflected, or a combination of both?
Would a L-shaped ground plane do the job, or would it make it worse? Maybe it would need some precise tuning.
Any ideas out there?
