Antipodal Vivaldi Antenna for On-chip Millimeter-wave Wireless Communication

This article introduces a millimeter-wave on-chip antenna using standard 0.18 mu m CMOS technology with multi-layer patterned grounding elements. The proposed antenna is designed by the type of the Antipodal Vivaldi Antenna According to the simulation results of the EM simulator, our proposed antenna can achieve a wide bandwidth from 70 to 122 GHz. Compared with S-11 < -10 dB and good impedance matching of the entire operating frequency band, it has obtained good radiation directivity in the end-fire direction. Furthermore, observed the gain range is -3.5 similar to -5.6 dBi At the operating frequency, and its efficiency is 16.5 similar to 18.8%, both relatively low due to the influence of metal and dielectric losses. The antenna we proposed has the advantages of simple structure, directivity compatibility with existing commercial complementary metaloxidesemiconductor (CMOS) technology and the overall antenna size of the on-chip antenna (AOC) is very compact, equal to 390 mm x 1010 mm.
