Ku-Band Low-Sidelobe Waveguide Array
The design of a 16-element waveguide array employing radiating T-junctions that operates in the Ku band is described.
Amplitude weighting results in low elevation sidelobe levels, while impedance matching provides a satisfactory VSWR, that are both achieved over a wide bandwidth (15.7-17.2 GHz).
Simulation and measurement results, that agree very well, are presented.
The design forms part of a 16 x 40 element waveguide array that achieves high gain and narrow beamwidths for use in an electronic-scanning radar system.
