Can you spot the difference? I had made several mistakes measuring 0.3 up to 1mm. These antennas were made on a precision mill able to place a 0.254mm bit down to the 0.0254mm. Needless to say my mistakes were way outside of tolerance… Thankfully our technicians are forgiving and kind!
This patch antenna works at 3.4 GHz and uses sequentially rotated feed to achieve circular polarization.
