| Oct 24, 2019 at 15:30 | comment | added | Marcus Müller | I'd probably actually start with the ARRL antenna book, if that still exists | |
| Oct 24, 2019 at 14:53 | comment | added | JoeyB | I have attempted to simulate this antenna on CST but the accuracy of the structure is too low. Hence I have to design my own circularly polarised antenna. Do you know of any books that can assist? | |

| Oct 23, 2019 at 18:33 | comment | added | Marcus Müller | @Joey I think slot antennas might fascinate you :) | |
| Oct 23, 2019 at 18:32 | comment | added | Marcus Müller | RF energy isn't transported in electrical circuits; it's transported in E-fields, often between conductors. Think of your coax cable: the wave is transported in the dielectric between inner conductor and shield. So, that disc is very much connected to the copper patches below: there's an E-field between these, and it radiates out from the slots in the disc. | |

| Oct 23, 2019 at 18:29 | comment | added | JoeyB | This will sound a bit silly, but the silver isnt physically connected to the circuitry so how does it then radiate the RF energy? | |
| Oct 23, 2019 at 18:26 | comment | added | Marcus Müller | ... That is the antenna. You literally removed the antenna before showing us the pictures... | |
| Oct 23, 2019 at 18:25 | comment | added | JoeyB | I added two additional pictures, do you know what is the purpose of the silver disc applied above the antenna? Have you come across something like this before or applied it to your designs? | |
