Experimental VSWR's and radiation patterns of an axial rectangular slot on conducting cylinders of varying curvature
Abstract
X band measurements of the VSWR's and radiation patterns of an axial rectangular slot on six conducting cylinders of different curvature are reported. The cylinders had ka (k is the free-space wavenumber and a is the cylinder radius) varying from infinity to 1.5. Measurements were performed both with the slot bare and with the slot covered by space cloth. For ka as low as 3, the effect of curvature was relatively small. Below ka of about 3, changes in the VSWR and radiation pattern were more pronounced, the pattern being relatively more sensitive to changes in ka than the VSWR.
