Abstract :
A given impedance load can be made matched to a transmission line by elementary stub tuner movements in a Smith chart. We now show that a given patch antenna can be made matched and broadband, by a similar stub tuner movements through replacing the impedance load with the center of the impedance locus loop of the patch.
