Solutions to overcome these challenges are offered and realized in digital 28-nm CMOS. A monolithic on-chip antenna is designed and optimized in the presence of rigorous metal density rules and other back-end-of-the-line (BEoL) challenges of the nanoscale technology. The proposed antenna structure further exploits ground metallization on a PCB board acting as a reflector to increase its radiation efficiency and power gain by 37.3% and 9.8 dB, respectively, while decreasing the silicon area up to 30% compared to the previous works. The antenna is directly matched to a two-stage low noise amplifier (LNA) in a synergetic way as to give rise to an active integrated antenna (AIA) in order to avoid additional matching or interconnect losses. The LNA is followed by a double-balanced folded Gilbert cell mixer, which produces a lower intermediate frequency (IF) such that no probing is required for measurements. The measured total gain of the AIA is 14 dBi. Its total core area is 0.83 mm 2 while the total chip area, including the pad frame, is 1.55 × 0.85 mm 2.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Keywords:||5G; Mm-wave; Nanometer-scale CMOS; 28 nm CMOS; Active integrated antenna (AIA); Antenna-on-chip (AoC); RF front-end; Low noise amplifier (LNA); Folded Gilbert cell mixer; On-chip transformer||DOI:||10.xxx||Other versions:||https://embc.embs.org/2019/||Language:||en||Status of Item:||Peer reviewed||Conference Details:||41st International Engineering in Medicine and Biology Conference, Berlin, Germany, 23–27 July 2019|
