Patch#

class ansys.aedt.core.modeler.advanced_cad.stackup_3d.Patch(application, frequency, dx, signal_layer, dielectric_layer, dy=None, patch_position_x=0, patch_position_y=0, patch_name='patch', reference_system=None, axis='X')[source]#

Patch Class in Stackup3D. Create a parametrized patch. It is preferable to use the add_patch method in the class Layer3D than directly the class constructor.

Parameters:

applicationansys.aedt.core.hfss.Hfss: HFSS design or project where the variable is to be created.
frequencyfloat, None: Target resonant frequency for the patch antenna. The default is None, in which case the patch frequency is that of the layer or of the stackup.
dxfloat: The patch width.
signal_layeransys.aedt.core.modeler.advanced_cad.stackup_3d.Layer3D: The signal layer where the patch will be drawn.
dielectric_layeransys.aedt.core.modeler.advanced_cad.stackup_3d.Layer3D: The dielectric layer between the patch and the ground layer. Its permittivity and thickness are used in prediction formulas.
dyfloat, None, optional: The patch length. By default, it is None and so the length is calculated by prediction formulas.
patch_position_xfloat, optional: Patch x position, by default it is 0.
patch_position_yfloat, optional: Patch y position, by default it is 0.
patch_namestr, optional: Patch name, by default “patch”.
reference_systemstr, None, optional: Coordinate system of the patch. By default, None.
axisstr, optional: Patch length axis, by default “X”.

Examples

>>> from ansys.aedt.core import Hfss
>>> from ansys.aedt.core.modeler.advanced_cad.stackup_3d import Stackup3D
>>> hfss = Hfss()
>>> stackup = Stackup3D(hfss)
>>> gnd = stackup.add_ground_layer("ground", material="copper", thickness=0.035, fill_material="air")
>>> dielectric = stackup.add_dielectric_layer("dielectric", thickness="0.5" + length_units, material="Duroid (tm)")
>>> signal = stackup.add_signal_layer("signal", material="copper", thickness=0.035, fill_material="air")
>>> patch = signal.add_patch(patch_length=9.57, patch_width=9.25, patch_name="Patch")
>>> stackup.resize_around_element(patch)
>>> pad_length = [3, 3, 3, 3, 3, 3]  # Air bounding box buffer in mm.
>>> region = hfss.modeler.create_region(pad_length,is_percentage=False)
>>> hfss.assign_radiation_boundary_to_objects(region)
>>> patch.create_probe_port(gnd, rel_x_offset=0.485)
