Abstract
This paper presents the concept of substrate integrated waveguide (SIW) technology along with superstrate layer, which is used to design a high gain antenna for 79 GHz automotive short range radar (SRR) applications. The maximum gain of a single antenna with superstrate layer is 14.6 dBi at 79 GHz, which is higher than the gain of a classical 2 × 2 array. It is found that the gain of a single superstrate layer increases nearly 8.78 dB at 79 GHz over its SIW base antenna. The CST simulated 2:1 VSWR bandwidth with superstrate layer is from 75.9 GHz to 81 GHz (6.46 %). The antenna patterns are found to be broadside all over the frequency band of interest. Also the results are verified using another simulation software HFSS.
