Abstract

This paper describes the design and development of an airborne ultralow sidelobe level antenna, starting from the design of individual linear arrays and the power divider network. The antenna employs radiating slots on broadwall of rectangular waveguide and is of traveling wave type. The various stages involved in the design process are described briefly. The experimental results including the far-field patterns, voltage standing wave ratio, and power division ratios are discussed in detail.
