Abstract
Utility of microwave bootlace lens is well established. For broadband and wide scanning network, it is required to op-timize and use features of this lens for better communication and scanning device. This report presents the design of a compact 2D bootlace lens with five focal feed for multiple beam forming. This design will help in reducing phase error and will provide power efficiency and better resolution during target tracking. This design will provide better aperture efficiency and scanning angle.

Summary
In many radar and communication applications, it is often required to scan a wide area using an antenna array. A multiple beam-forming network is required to control the amplitude and phase at each element of the antenna array. Ruze [1] suggested a lens for wide-angle scanning. Rotman and Turner [2,3] suggested modification in Ruze’s lens to improve the scanning capabilities. Wide-angle scanning capabilities of these lenses are well established [4,5,6]. Bootlace lenses have traditionally offered great design flexibility without the excessive cost and reliability difficulties of phased array. This present report proposes to improve the current lens technology by developing a five focal point lens with scanning capability in a plane. The entire aperture is used for all beams, providing optimum efficiency for this antenna
