Abstract—A review of the design and analysis techniques reported so far for Bootlace type lens and its origin the Rotman type lens has been presented. The basic design and the improvement with its implications and adoptions are presented with the justification. The basic bootlace lens with the modifications reported with improvement and their characteristics is also presented with mathematical approach. The parameters and methods, which are of importance in the design and analysis of the work, are compared and performance thereon is considered for practical approach and fabrication results of some of the tested designs are also investigated. The basic design of microwave lens is Rotman lens and modifications have brought the new concept of bootlace lens due to its specific design and look as of open lenses of military boot. This analysis has given us direction for new approach in design.
Index Terms—Antenna array, Bootlace lens, Path length error, Rotman lens.
