FUNCTION: Creates the parameterized geometry of a slot-coupled rectangular patch antenna in the project workspace
NOTES, SPECIAL CASES OR EXCEPTIONS: This wizard creates a substrate with two dielectric layers, which are separated by a PEC ground plane hosting a coupling slot. The upper layer hosts a rectangular patch antenna. The bottom layer hosts a microstrip feed line with an open stub, which is extended past the slot location. The total dimensions of the square patch are set equal to 0.5 47 times the effective dielectric wavelength, which can be changed. The length of the open stub beyond the slot location is set equal to a quarter guide wavelength, which can be changed, too.

FUNCTION: Creates the parameterized geometry of a narrow rectangular slot in a ground plane
NOTES, SPECIAL CASES OR EXCEPTIONS: This wizard simply creates a linear slot in a ground plane using Boolean subtraction.

MENU: '''Tools → Antenna Wizards → Linear Slot Antenna'''
MODULE(S): [[EM.Tempo]], [[EM.Picasso]]
FUNCTION: Creates the parameterized geometry of a slot antenna in a ground plane
NOTES, SPECIAL CASES OR EXCEPTIONS: In [[EM.Tempo]], the wizard creates a slot antenna excited by a lumped source on a short line across the slot. In [[EM.Picasso]], the wizard creates a slot antenna on a slot trace fed by a magnetic gap (current) source. The length of the slot is set equal to a half the effective dielectric wavelength, which can be changed.
