Another fantastic design by Maarten Beart and his co-worker Robin Theunis!
So many things make this design a game changer, not only does this single patch work for both LHCP and RHCP but also has a much higher axial ratio than most other FR4 based Patch antenna.
Disclaimer the photos are of our prototype antennas but the produced revision will look a bit more polished.

So the first thing that really sets this antenna is that it can be used for both RHCP and LHCP.
We include a coax extension and a 50ohm dummy load for the best potential RF performance.
One reason we have not had a patch antenna up until this point, is that the axial ratio was not very good especially off axis. (Many other antennas become more of a linear antenna when flying just off of center) This new design from Maarten/Robin maintains its axial ratio very well at many different angels and has a very smooth radiation pattern!
With 9.4db of gain you will be able to punch through more and get longer range than many other patch antennas on the market.
