RFIC measurement and off-chip antenna excitation through proximity coupling at 60GHz

Off-chip antenna excitation through magnetic inductive coupling at 60GHz has been proposed to facilitate the industrial RFIC measurement or the antenna connection to the RFIC chip. To verify the concept, a slot antenna at top layer of the PCB was excited through magnetic coupling from the RFIC chip set at the proximity of the antenna. Minimum return loss of -17dB, gain of 6dBi, and bandwidth of 7GHz at 60GHz achieved through simulation to serve all the applications at unsilenced 60GHz frequency. The case can be extended to multi-port or MIMO RFIC chips by using antennas with orthogonal polarization.
