Design of a 60GHz high efficiency virtual loop antenna on low resistivity silicon substrate

The design is presented of high efficiency virtual current loop antenna (VLCA) for use on CMOS ICs technology that promises to integrate a complete 60 GHz system on single chip that combines a good performance in both bandwidth and radiation efficiency. The design was based on intensive electromagnetic simulations using HFSS software package. Different virtual loop antennas have been designed for different frequencies on a low resitivity silicon substrate and simulated. The simulation results show that the antenna achieved a radiation efficiency of 77% and a gain of 1.43 dB at 60GHz.
