The design of waveguide Slot Taylor circular arrays

Two dimensional arrays formed by arranging a number of linear slotted waveguides side-by-side are presented. Theory, synthesis procedure, and implementation of the two dimensional Taylor Slot Array are demonstrated. The performances of the two dimensional Taylor Slot circular array with 972 slots in the ka-band at the center frequency of 30 GHz are demonstrated. A less than 1.51 dB input voltage standing-wave ratio (VSWR) with the band width of 600 MHz is achieved. At the center frequency 30 GHz, main beam is 35.48 dB with a 25dB sidelobe level of the H-plane and 21.3 dB sidelobe level of the E-plane are also achieved.
