1. A millimeter wave (MMW) antenna array, comprising:

  • a continuous transverse stub (CTS) radiating aperture comprising a set of spaced continuous transverse stubs, each having a longitudinal extent;

    an excitation source for providing excitation signals in a MMW frequency range;

    a feed system coupled to an excitation source for exciting the stubs with MMW electromagnetic energy having a linear phase progression along the longitudinal extent of the stubs to produce an array beam which can be scanned over a beam scan range by changing the frequency of the excitation source.
