A Dual-Band Antenna-On-Chip Using Microbumps

A dual-band antenna-on-chip (AoC) with a loop-type antenna at 120 GHz and a 1-by-2 dipole-type array at 280 GHz realized in a shared structure was presented. The AoC utilizes micro-bumps in a standard flip-chip assembly process, showing radiation gains of -5.71 dBi and 7.32 dBi, as well as maximum efficiency of 13.56% and 52.14% at two bands, respectively. It is promising to be applied for millimeter-wave and THz integrated sensing and communication.
