Abstract:

A class of slotted arrays that utilizes the principle of dielectric loaded waveguide is described. The physical design of these arrays for operatioon at C-, S-, and L-band frequencies is characterized by their unusually small volume. Design techniques, dielectric material characteristics, and theoretical concepts for practical array-designs are discussed. Simplified methods of construction are outlined, and the performance of each design type is presented. This includes data on design parameters, voltage standing wave ratio, and radiation pattern characteristics. These dielectricloaded slot arrays offer substantial savings in volume, weight, and overall cost when compared with their conventional counterpart. A typical design 0.125 x 1.20 x 10.5 in. at 5.4 Gc has a gain of 12.0 db, 16-deg elevation beamwidth, sidelobe level below 22 db, and a VSWR less than 1.5 over a 10-percent bandwidth. Author
