  1. what type of PCB, thickness .. ??
  2. Yes, but on PCB needs other dimensions ... !!!
  3. The screw is not visible ...???
  4. And what is it ...?
  5. okay,but this is reality....
  6. Let's see, it might be...!!!!
  7. you have to make an adaptation line with PCB...
  8. connection with 50ohm coaxial cable...??
  9. ,,,so...??? 60mm outer diameter ,,,or so...
  10. I will simulate such an antenna,,,!!!
  11. "no, no, I want to see how you typed spirals between them ///
  12. ,,, and how do you make the connection between the spirals .. ??
  13. 16,,,,19dBi it can only be obtained with at least 8 patches....!!!!!
  14. On this forum seems to be the sizes of these antennas ,,, I do not know for sure !!!
  15. ...these calculations do not correspond to reality....!!!!
  16. The schematic diagram of the antenna is shown in Figure 1. Two or one sectoral slots are made on the patch surface. The presence of the sectoral slots on the patch causes the antenna to resonate at two adjacent frequencies, which results in the enhancement of the impedance bandwidth
  17. ,,,please translate it...!!!!
  18. ...this one....
  19. Thank you, but tell me what it"s the distance between the patches...??!!! ,,,and the length of the impedance adjustment lines?
  20. More details, please....!!!
  21. I'll try to do a simulation on 2442MHZ of this ...
  22. This quadrate antenna is for 2,442 GHz...??
