Make your own 2.4 GHz Circular Polarized Clover Leaf antenna

Make your own 2.4 GHz Circular Polarized Clover Leaf antenna.
This is a 2.4 GHz circularly polarized omnidirectional antenna.
Thanks very much for your detailed instructions regarding these wifi antennas.Very very helpful. <br> <br>I have one question, which I have been unable to find an answer for. I would like to attach one of these designs to the swivel mount of my existing antennas. When I open them up, I see a sheathed cable going from the SMA connector, to a metal can (I believe that is a length of 1/2 wave), and then protruding out of the top foranother 1/2 wave. At exactly what point would I attach this antenna to, in order to not compromise its performance? I understand the exactness of the lengths, and am somewhat confused as to whether I need to add a &quot;decoupler&quot; or not. <br> <br>Any information in regards to this would be greatly appreciated. <br> <br>Thanks...Eric
Your tutorial just solved years worth of tx and rx problems. Cheers.
Nice design, it seems a boat's propeller. <br> <br>What is its advantage over a standard one? Pardon, maybe you said it on the video, but I don't understand spoken English.
The advantage over a stranded rubber duck antenna is its circular polarization. A rubber duck (dipole) is vertically polarized. A vertically polarized signal will flip every time it hits a reflective surface. When it does this it will lose up to 1db of gain. A circular polarized signal does not flip, so does not suffer from this loss. <br>Hope this helps <br>
OK, thanks for your explanation. <br> <br>I don't know if I understood: Is it to say that the waves go upward? Could be fixed this using a 45&deg; mirror above of the antenna?
