Starting with a classic circular polarized antenna design from the 1940’s called the Lindenblad, with modern design tools and innovative manufacturing techniques, it brings this classic design to the 21st century.
Using a unique combination of microstrip and ladder line transitions, excellent RF matching is achieved to allow more of the signal to be transferred between the antenna and the feed line. The dimensions, angles, materials, and locations of all the elements were then adjusted using the modeling software to yield the best results possible.
The case is made of lightweight but strong polycarbonate material, allowing for a robustly built antenna that can take the abuses of standard FPV use. The antenna design itself has been optimized to work in conjunction with the case material to prevent unnecessary RF losses due to changes in the material surrounding the antenna.
