A Design of Ultra-Wideband Rotman Lens

An ultra-wideband Rotman Lens with wide coverage is designed. Twenty-five stable radiation beams own a scanning range between ±45° with a low crossover level. To ensure the designed Rotman Lens has the good ability, the array factor was analyzed from the measured s-parameters. An excellent agreement...

Summary:An ultra-wideband Rotman Lens with wide coverage is designed. Twenty-five stable radiation beams own a scanning range between ±45° with a low crossover level. To ensure the designed Rotman Lens has the good ability, the array factor was analyzed from the measured s-parameters. An excellent agreement between the measurements of the fabricated Rotman Lens and the simulated results is observed.
