Abstract : This article demonstrates the design of a miniaturized, ultra-wideband monopole on-chip antenna for automotive radar application. The proposed antenna achieves significant impedance bandwidth of 28.4 GHz (S 11 < -10 dB from 8.3 GHz to 36.7 GHz) with centre frequency of 24 GHz. It achieves minimum return loss of around -32 dB at 24 GHz that clearly indicates good impedance matching of the antenna with the source. The proposed antenna offers peak gain of -3 dBi at 28 GHz. Compactness (size of 3.8 mm × 4 mm × 0.676 mm) and simple design layout is the main attractiveness of this research work. The 3D antenna structure has been analyzed using ANSYS HFSS v17. Silicon wafer with thickness of 675 µm is used as a substrate of the proposed antenna.
