ICON: [[File:us_patch_icon.png]]
MENU: '''Tools → Antenna Wizards → Microstrip-Fed Patch Antenna'''
MODULE(S): [[EM.Tempo]], [[EM.Picasso]]
FUNCTION: Creates the parameterized geometry of a microstrip-fed rectangular patch antenna in the project workspace
NOTES, SPECIAL CASES OR EXCEPTIONS: In [[EM.Tempo]], the patch antenna is fed by a lumped source on a short vertical PEC line. In [[EM.Picasso]], the patch antenna is fed by a probe source on a short vertical PEC via. In both modules, the dimensions of the square patch are set equal to 0.47 times the effective dielectric wavelength, which can be changed.
