Abstract : Short-backfire (SBF) antennas can be simply converted into highly directive and efficient array elements. Each SBF element is the equivalent of four to six dipole elements of conventional multielement arrays. Models of two-, four-, and eight-element SBF arrays have yielded gains of 17, 19, and 22 dB, respectively. Radiation patterns are presented, including the sum and difference patterns in the two major planes (E and H), as well as those for diagonal cuts at plus or minus 45 degrees. All physical dimensions are given in wavelengths so that each model can be easily scaled for any desired frequency. (Author)
