Four-element short-backfire (SBF) arrays have been shown to yield maximum gains of approximately 20 dB. The influence of parameter variations on the array patterns has been experimentally determined. Specific parameter values required to yield certain pattern characteristics--for example, highest gain, lowest sidelobe level, equal half-power beamwidth, or equal beam shapes in both the E and H planes--have been established. Tables of the normalized design parameters are given for construction purposes. All array dimensions are indicated in wavelengths so that each model can easily be scaled for any desired frequency range. (Author).
