On-Chip 60 GHz Coplanar Folded Slot Antenna with Air Cavity and Reflector
2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI), 2023A 60 GHz coplanar folded slot antenna (CFSA) using a silicon-on-insulator substrate, an air cavity, and a back reflector is proposed. The proposed CFSA has a center frequency operating at 60 GHz with a −10 dB impedance bandwidth of 3.3% (58.9-60.9 GHz ...

IEEE transactions on microwave theory and techniques, 2021
In this article, a series of filtering cavity slot arrays using high-order modes are investigated. It is found that each unit of the cavity slot arrays in the proposed high-order mode resonator is in phase with the same amplitude, which helps enhance the
