ABSTRACT:
A specified pattern slotted waveguide antenna is achieved by controlling the amplitude and phase of each slot of the array. The amplitude and phase of each slot is controlled by selecting the proper spacing between slots, the proper offset or slanting of each slot from the long axis of a waveguide, and the proper termination of the waveguide. The selection technique considers both the incident and reflected voltages in the waveguide to produce the desired amplitude and phasing at each of the slots, and also provides a proper load to a generating signal at center frequency.
