How to compute the location of the antenna when I rotate it?

  1. Jan 19, 2017 #1
    Hi group,

    I have a question regarding to detect the location of the antenna.
    I read this link: https://en.wikipedia.org/wiki/Plane_wave
    In the "Complex exponential form" part, the equation:
    U(r,t) = U0 * exp(j*(k.r - w*t) as the function of location and time
    U0 = A0 * exp(j*phi) : A0 and phi are amplitude and phase respectively.
    From U0, I can write down a complex number x and y (still in time domain)
    x and y should be vector on the complex coordinate.

    Now, I need to define value of amplitude and phase base on value of x and y. But I do not know x and y.
    When I rotate the antenna, can I define the position, amplitude and phase?

    I hope any one can give me suggestions.

    Thank you.

    I do not understand the question, what you are trying to do, the relevance of the equations or the equipment you are using.
