A Patch array antenna for 60 GHz package applications

This paper has presented array feed line structures that are suitable for mmWave applications where microstrip lines do not function very well. Since CPS and CWP lines are used, the feed line loss is reduced tremendously so large arrays are possible for mmWave applications. Although the corporate-fed patch array is presented here, the feed line structures can be used for slot arrays or a combination of series and corporate-fed patch arrays. Since air-bridges are used in the feed line structures, thin-film technologies are preferred manufacturing choice of these arrays.
