    Hello sir
    while going through the topic of patch antenna I came across a
    statement which goes like-"the current at the end of the patch is
    zero, its maximum at the center of the half wave patch & zero at the
    beginning of the patch ",which led to a number of questions popping
    up in my mind & unfortunately none of them being exactly answered by
    the references being mined by me till yet .I've got a little idea that
    this phenomena has got something to do with the wave nature of the AC
    RF signals being supplied to the antenna but will you please bother to
    explain this in context of the amplitude & magnitude of the surfacial
    current dirtribution & also that does the current distribution vary
    sinusoidally with time?sir please channelise me in this direction,for
    googling doesn't seem to have shed a whole lot of light.thnku...

    As I recall, my education on this and related topics spanned two semesters at MIT. That was fifty years ago, and a lot of theory and practice have been developed since. It's not a simple topic.

    For a broad-brush introduction to antenna theory, I'd recommend "The ARRL Antenna Book". There are a couple of mentions of patch antennas.
