Abstract:
Major shortcoming of current silicon-based millimeter-wave mmW on-chip antennas is the low radiation efficiency 5-10. In this paper, we propose a phased antenna array on silicon substrate with the radiation efficiency 80 at 60GHz. This is achieved by suspending radiating elements using micro-electro-mechanical systems MEMS processes, thus creating a low-Epsilon r substrate of air instead of lossy silicon substrate. The designed 5X5 element array is well matched at 60 GHz with the -10 dB bandwidth of 2 GHz. The peak realized gain for the 5X5 array is 19.7 dBi with the gain reduction of 4 dB at the maximum scanning angle. Moreover, the scanning volume of the designed antenna is or - 45 deg in H plane and or - 48 deg in E plane. As an on-chip phased array, the designed array can be monolithically integrated on a silicon substrate. Moreover, unlike other arrays, it satisfies high realized gain and moderate scanning volume in both E and H planes, making it desirable for next-generation wireless systems.
