| description | <p>This paper presents a single-layer SIW longitudinal slot array antenna optimized for high gain and low side lobe levels (SLL) in the W-band, designed for LMRR (Long Medium Range Radar) applications. This design enhances detection range at high frequencies. It also provides a wider azimuth field of view (FOV) at lower frequencies. The approach improves compactness and reduces costs. It eliminates the need for multiple antennas in different radar ranges. The system includes two band pass filters (BPFs) and one power divider. These components integrate into four antenna arrays, each with six slots. The results show a 4.6 dB gain improvement between lower and higher frequency bands. The antenna extends the maximum detection range by 168 m for a vehicle with an RCS of 10 dBsm in a lossless system. Additionally, the study analyses the normalized admittance of the antenna. It examines the effects of slot length, width, and displacement on conductance and susceptance. These findings confirm the antenna's efficiency for radar applications. A comprehensive tolerance analysis was performed to assess the proposed design's robustness under variations in key parameters.</p> |
