Abstract : A description is given and results are presented of a limited scale model experimental investigation of a unidirectional, vertically polarized log-periodic antenna. This type of structure is called the coaxial-fed monopole array. This structure is of interest due to the fact that it exhibits the general characteristics thought to be necessary for a basic element of the Wide Aperature Radio Location Array (WARLA). The investigation was principally directed toward finding a structure having a particular radiation pattern, after which this particular structure was investigated in detail to ascertain and optimize its impedance performance.
