    Will this feeding mechanism right/work for 8*1 patch antenna array ?

    I am trying to design a feeding mechanism for 8 patch antenna array.

    I have used 50 ohm transmission lines followed by a 70.71 ohm quarter wave transformers(circular shape). Please see attached image for more clarity. I have made inset feed patches. They have good performance at 2.3 Ghz.

    It will be a great help if you can let me know any fundamental issues in the design or if there is a better way to design feeding for patch array.

    Regards

    The Wilkinson power divider is a pretty standard architecture. The only comment I have is that you could make it more space efficient with a N-branch power divider, but those are more difficult to make.

    Looks good as is. Good luck with the layout!!

    It seems fine. The 70 Ohm lines should off course be quarter wavelength at your desired frequency. The 50 Ohm ones though can be made smaller (if you want to).
