Modified design of bootlace lens for multiple beam forming

Abstract

As of now, utility of microwave bootlace lens is well established. For broadband and wide scanning network, it is required to optimize and use features of this lens for better communication and scanning device. This paper presents the design of a compact bootlace lenses for multiple beam forming. Equations to design the lens have been given. The designed lenses has been fabricated and tested. The measured results are in close agreement with the designed values. Key words: Multiple beam forming, antenna design, bootlace lens, wide area scanning, rotman lens
