Abstract : The directional characteristics and input imped ance of a two-element Yagi-type array in a paral lel-plate region were studied. The optimum values of the tuning reactance and inter-element spacing at which the parasite gives the best performance either as a reflector or as a direc tor were obtained. The radiation fields in the directions away from and towards the parasite, and the input impedance to the array were meas ured experimentally and found to be in good agreement with theory. (Author)
