Abstract :
77GHz Automotive radar based on SiGe technique is the hot topics. The optimal matching in the RF part of the automotive radar should be solved and considered firstly. Left hand material(LHM) has special properties such as low loss, negative phase velocity. The paper focus on designing a new transmission line which is made by LHM and RHM (right hand material) together. We analysis the theory of the TL (transmission line) based on compositing LHM and RHM together, then design the match circuits based on the TL. Moreover, the simulating results of the circuit based on the special TL are shown. Lastly, the possibility of using the TL to match at the automotive radar system is valued.
