A radial line patch antenna (RLPA) with external feeding phase control is presented. The coupling mechanism from the radial waveguide to the patches is achieved by inner small microstrip lines. The fed amplitude is controlled by the dimensions of these lines, whereas the phase is modified by outer t...
