A WIDEBAND VERTICAL INCIDENCE RADIO LOCATION ARRAY
Abstract
The feasibility of designing a wideband, high-efficiency vertical incidence antenna capable of providing either a single or split beam centered on the zenith has been investigated by the use of scale models. It was found that two log-periodic dipole array elements arranged in an H-plane array fed properly over ground would provide the required beam configuration in the H-plane. A performance investigation as a function of the various design parameters was conducted where the design parameters' variation was limited to some extent by the practical considerations involved in an antenna designed for the 2 to 32 Mc frequency range. It was found that there existed a combination of parameters which would provide a reasonably good compromise between ideal pattern and impedance performance, the impedance performance being the more critical of the two. During the parameter investigation some interesting antenna feed problems were encountered and investigated to the extent of solving the problems for the special applications involved in the model studies being conducted.
