Abstract:

A large number of numerical results for Yagi backfire antennas are presented, from which the influence of a variation of the antenna parameters may be deducted. The results were obtained by means of a previously described theory for backfire antennas with dipole elements, and the numerical computations were carried out on a digital computer. Samples of the numerical results were compared with experimental results obtained in a radio anechoic chamber. Finally, the influence of small changes in the general Yagi backfire antenna structure, such as changing the single dipole reflector elements into a half-transparent or solid conducting plate or changing the array of equally long dipole director elements into a tapered array, was investigated.
