Thank you for the reference, I have found some useful information about patch antenna structures, design methods and CAD software. But unfortunately, I have not found any information about historical development of patch antennas.

These antennas were used back around 1960 in space rockets and on military tanks. The first was for wind resistance reduction and the second for reducing battle field damage to communication systems.
