Hi, Gurus,
I need to design a microstrip antenna for 60GHz mmwave.
And the area is limited to 6mm*6mm, not including the matching subs.
So which type has the maximum gain? Antenna Array is also ok, only the total area is limited to the aforesaid.
I design a simple square antenna, which has 4.5dB at 60GHz.
I know there should be some type or pattern antenna has the more gain.
I just want to the pattern, so that I can build the model to further optimizing.
Sincerely,
Tony Liu
 

Three parallel λ/2 monopoles, spaced at λ/2 distance, and feeded with the same phase at their ends, will give at least 6dB of gain on the broadside direction. The drawback is that the feeding is a bit more complicated than of a single patch, but not so much because all three ports use the same phase.
Theoretically all three monopoles should fit on the available area. If not, try to reduce the spacing between elements and retune for highest gain.
