Abstract:

A short backfire antenna incorporating an open-ended waveguide as its feed mechanism has been measured experimentally in three different structural configurations. A complete set of curves describing the directivity, sidelobe levels, and half-power beamwidths as a function of frequency, as well as a few of the more important radiation patterns, are presented for each case. The effects obtained by varying parameters such as disk diameter and waveguide spacing are discussed, especially with regard to the directive gain and area illumination efficiency. Recommendations are made on techniques for fabrication, impedance-matching, and arraying antennas of this type for possible airframe applications. Author
