Gain Enhancement of On-Chip Antenna at 60 GHz Using an Artificial Magnetic Conductor

Wireless data communication within and between CMOS chips at 60GHz is very attractive for short range wireless transmission. The objective of the work is to enhance antenna gain and improve the radiation efficiency with the use of the Jerusalem-Cross Artificial Magnetic Conductor (AMC) to mitigate the effects of the silicon and improve data transmission within and between chips. The Yagi is optimized for an endfire radiation in the plane of the chip. Its performance is studied when it is placed in the center of the chip and along the edge, with the AMC layer extending only below the feed system and then compared when it extends over the entire chip. The results show that the AMC layer improves the gain by 2.5 dB and radiation efficiency by a few percent. All simulations are performed using ANSYS HFSS.
