V-Band Polarization Reconfigurable CMOS Antenna-on-Chip Efficiency Enhancement Using AAMC

Performance-Issues-Mitigation-Techniques for On-Chip-Antennas – Recent Developments in RF, MM-Wave, and Thz Bands With Future Directions

“…the use of 180 nm SOI CMOS and off-chip reflector has been proposed for Q-band applications in [106]. A 180 nm CMOS based polarization reconfigurable AoC at V-band [83] makes use of the asymmetric AMC as a performance enhancement method and gets a 1 dBi raise in gain and 10 % rise in the radiation efficiency. Two DRA backed antenna arrays, one 2 × 1 and other 4 × 1, have been proposed in [92] with significant gain values.…”

“…Based on these verifications, the authors used the asymmetric AMC for the design and fabrication of a 60 GHz circular AoC using 180 nm CMOS process, which produces radiation efficiency, gain, and front-to-back ratio (FBR) of 49 %, 0.25 dBi, and 12.8 dB, respectively. The authors in [83] have also utilized asymmetric AMC for a V-band polarization reconfigurable AoC design using 180 nm CMOS process and achieved 1 dBi increase in the gain and 10 % rise in the radiation efficiency. Several other AMCs-based AoCs at MM-Wave are reported in recent literature whose detail can be seen in Table 2.…”

Current trends and future perspective of designing on-chip antennas

“…This zero phase reversal of the waves produces constructive interference and contributes to enhanced radiation performance of the antenna. Different techniques to employ the zero phase reversal theory of AMC have been introduced for enhancing the radiation performance of OCAs [43][44][45][46][47]49]. A two-layered dipole OCA (connected using vias) is fabricated with a 14 × 7 unit cells of AMC ground and the gain enhancement of 5 dBi with 63% of efficiency is observed [43].…”
