Comparison of 60 GHz quasi-Yagi antennas using different microstrip-to-CPS transitions

This research has demonstrated that the radial stub based microstrip-to-CPS transition can affect the directivity of printed quasi-Yagi antenna operated in 60 GHz due to it cannot provide 180 degree phase change. The results can help to solve the directivity issue that occurred in preceding design. The next step of work will focus on fixing the directivity problem, optimizing and fabricating the previous device using results obtained from this work.
