A Non-Focal Rotman Lens Design to Support Cylindrically Conformal Array Antenna
Keywords:
Beam Forming Networks (BFNs), conformal array antennas, Particle Swarm Optimization (PSO), Rotman lensAbstract
Rotman lenses offer broad bandwidth, and render to planar structures making them ideal for a variety of applications. However, a limitation of the Rotman lens is that it is based on the assumption of supporting linear arrays. In this paper, we develop a new design technique to enable the lens to feed a conformal array antenna.
