Hi, Gurus,
I opted an antenna array, as the antenna picture.
And its spec is as the attachemnt sidelobe.
You can notice the sidelobe is only -13dBc. Someone said it better be -15dBc.
So how to config the opt to decrease the sidelobe of the antenna array? Especially the left side sidelobe?
Thanks a lot.
Tony Liu

Decrease a bit the spacing between elements (from λ/2) and the grating lobes should minimize.
