Bowtie antenna synthesis#

This example demonstrates how to synthesize a bowtie antenna using the BowTieRounded class. It initiates AEDT through PyAEDT, sets up an empty HFSS design, and proceeds to create the antenna.

Perform required imports#

Import the antenna toolkit class and PyAEDT.

[1]:

import tempfile

[2]:

import ansys.aedt.core

[3]:

from ansys.aedt.toolkits.antenna.backend.antenna_models.bowtie import BowTieRounded

Set AEDT version#

Set AEDT version.

[4]:

aedt_version = "2025.1"

Set non-graphical mode#

Set non-graphical mode.

[5]:

non_graphical = True

Create temporary directory#

[6]:

temp_dir = tempfile.TemporaryDirectory(suffix="_ansys")
project_name = ansys.aedt.core.generate_unique_project_name(root_name=temp_dir.name, project_name="bowtie_example")

Create antenna object only for synthesis#

Create antenna object.

[7]:

oantenna1 = BowTieRounded(None)
print(
    "Arm length: {}{} at {}{}".format(
        str(oantenna1.synthesis_parameters.arm_length.value),
        oantenna1.length_unit,
        oantenna1.frequency,
        oantenna1.frequency_unit,
    )
)

Arm length: 3.7mm at 10.0GHz

Change synthesis frequency#

Modify resonance frequency and modify parameters.

[8]:

oantenna1.frequency = 12.0
print(
    "Arm length: {}{} at {}{}".format(
        str(oantenna1.synthesis_parameters.arm_length.value),
        oantenna1.length_unit,
        oantenna1.frequency,
        oantenna1.frequency_unit,
    )
)

Arm length: 3.03mm at 12.0GHz
