A Gain Levelling Technique for On-Chip Antennas Based on Split-Ring Resonators

This paper introduces a gain enhancement technique for monolithically integrated antennas. Such devices can suffer from dips within their operating bandwidth due to standing waves arising in the die or caused by interactions with other on-chip components. In this work, it is shown how these effects be significantly mitigated parasitically coupling square Split Ring Resonators (SRR) fed antenna. The SRRs geometry and master antenna set such way that they create an additional resonance cancels drops improves impedance matching. proposed configuration has been validated using W-band monopole standard $0.13~\mu \text{m}$ SiGe BiCMOS process. Thanks approach, was possible compensate drop of about 7 dB at 85 GHz. As result, experimental assessment showed maximum measured 1.61 81.5 GHz 77 87
