    1) No.

    2) Other dimensions are required for 0.35mm copper sheet.

    3)The antenna simulated by me , works just as well for the 5.0-5.5 GHz frequency range.

    thanks

    In our area, only PCBs with a thickness of 1.6 and a thickness of 0.35 can be found
    Is it possible to design for this type of material?

    ,,, that would be ... !!!!

     

    Thanks, my friend
    I want this antenna for fpv
    I will definitely make your design and test it on the UAV
    I bought the antenna you see in the picture
    I haven't tested it myself yet, but apparently it works great
    My friends tested and reached a range of 30 km with a power of 1 watt
    I do not need this amount
    Coverage is more important to me
    For example, with two diversion receivers and 90 degree coverage and 10 dbi gain for 10 km distance
    I have a few questions to make this antenna
    1. If I use fr4 with a thickness greater than 0.8, like 1.6 and add to the height will the antenna have the same performance? Or do I want to use a steel plate instead of its FR4?
    2- Is the thickness of copper 0.25? Is there a problem for me to use 0.35? (Finding a 0.25 board is really hard)
    3- Is it possible to design based on multiples of lambda? Because the network may be busy, I have to switch to Frequency 5280
    Thank you in the end

    ,,,no,

    if you want for the 5.2 GHz frequency ,tell me...?!

    Hi admin

    I know the date of this post is very old, but if possible, do the design for the 5200 frequency as well

    i want to make it 
    thank you
