A LOG-PERIODIC CAVITY-BACKED SLOT ANTENNA.
Abstract
It has been shown that it is possible by considering the dual of the successful log-periodic dipole arrary to produce a broad-band antenna in the form of a cavity-slot radiator. It has thus been demonstrated that principles for successful operation in the free-space log-periodic dipole array may be usefully applied to the design of a broad-band antenna mounted below a conducting ground plane screen and radiating through it. Although design data are not yet available, it has never theless been shown that such an antenna is entirely feasible. At the present stage of development, the basic problem is that of finding a model which operates satisfactorily and then to vary its parameters to discover the predict their roles and significance. Further theoretical analysis of the component parts of the cavity-slot antenna as well as the composite structure should aid materially in perfecting future models. (Author)
