A fast calibration method for slide-screw impedance tuners employs a reduced calibration algorithm, which creates appropriately distributed calibration points over the Smith chart compatible with already existing interpolation and tuning algorithms for high accuracy and high-speed impedance tuning. The method uses one vertical scaling of the tuning probe followed by a limited number of vertical positioning operations at pre-set horizontal intervals and applies this data to generate accurate interpolated high-density tuner calibration data points at a fraction of previously required calibration times.

In an example embodiment, an azimuth combiner comprises: a septum layer comprising a plurality of septum dividers; first and second housing layers attached to first and second sides of the septum layer; a linear array of ports on a first end of the combiner; wherein the first and second housing layers each comprise waveguide H-plane T-junctions; wherein the waveguide T-junctions can be configured to perform power dividing/combining; and wherein the septum layer evenly bisects each port of the linear array of ports. A stack of such azimuth combiners can form a two dimensional planar array of ports to which can be added a horn aperture layer, and a grid layer, to form a dual-polarized, dual-BFN, dual-band antenna array.
