Novel Method for Numerically Accurate Analysis of Printed Rotman Lens Antennas
Abstract
Broadband multiple beam electronically scanned antennas are a key component of the Future Combat Systems. where heavy armor is traded in by active protection systems, and various radar and communications capabilities are integrated into a single Multi-Function RF system. Due to their inherent broadband properties. Rotman lenses have received attention in applications. However, these lenses are electrically large structures. making it difficult to be simulated with reasonable accuracy so that a quick design and fabrication can be achieved. In this paper. we present a novel hybrid technique for the analysis of printed lenses that offers tremendous savings in the required computational resources, when compared to the existing general 3D and 2D electromagnetic simulation tools.
