In this article from the International Journal of Antennas and Propagation, fabrication of a high resistivity silicon based microstrip Rotman lens using a lift-off process is presented.
Electromagnetic simulation has been used by RF engineers for many years to aid the design of automotive radar sensors, but the increasing demands of advanced driver assistance systems (ADAS) are changing the methods used. This paper introduces FDTD’s advantages for automotive radar circuit and systems level designers, including simulation of very large problems, more efficient memory requirements, and the ability to reveal sources of coupling.
This whitepaper demonstrates how XFdtd's time-domain approach enables rapid development by allowing engineers to determine the performance of a fully detailed sensor model installed behind a piece of fascia without needing to build prototypes and run tests in an anechoic chamber. The analysis of a 25 GHz sensor frames the discussion.
This paper outlines the advantages of FDTD EM simulation for analyzing antenna-in-system designs that include both the antenna package and the automobile body features surrounding the device. An XFdtd simulation of a radar mounted in the rear bumper of a sedan provides the framework for the discussion.
