Abstract : A large number of numerical and experimental results showing the influence of a variation of the antenna parameters on the radiation properties of a short-backfire antenna are presented. These results may be very useful for the design of such antennas. The numerical results were calculated on a digital computer using a previously published theory for backfire antennas with dipole elements. The experimental results were measured in a radio anechoic chamber. Other numerical results were obtained, which show that the radiation properties of the short-backfire antenna correspond to those of open resonators. Finally, a number of computations were carried out in order to investigate the possibility of applying the short-backfire antenna as the excitation system of a Yagi antenna. (Author)
