:class:`RectangularPatch` ========================= .. py:class:: pyedb.libraries.rf_libraries.planar_antennas.RectangularPatch(edb_cell=None, target_frequency: Union[str, float] = '2.4Ghz', length_feeding_line: Union[str, float] = 0, layer: str = 'TOP_METAL', bottom_layer: str = 'BOT_METAL', add_port: bool = True, permittivity: float = None) Rectangular microstrip patch antenna (optionally inset-fed). The class automatically determines the physical dimensions for a desired resonance frequency, creates the patch, ground plane and either an inset microstrip feed or a coaxial probe feed, and optionally sets up an HFSS simulation. :Parameters: **edb_cell** : :obj:`pyedb.Edb`, :obj:`optional` EDB project/cell in which the antenna will be built. **freq** : :class:`python:str` or :class:`python:float`, :obj:`default` "2.4GHz" Target resonance frequency of the patch. A string such as ``"2.4GHz"`` or a numeric value in Hz can be given. **inset** : :class:`python:str` or :class:`python:float`, :obj:`default` 0 Inset depth for a 50 Ω microstrip feed. A value of 0 selects a probe (via) feed instead. **layer** : :class:`python:str`, :obj:`default` "TOP_METAL" Metallization layer on which the patch polygon is drawn. **bottom_layer** : :class:`python:str`, :obj:`default` "BOT_METAL" Metallization layer on which the ground polygon is drawn. **add_port** : :ref:`bool `, :obj:`default` :data:`python:True` If True, create a wave port (inset feed) or lumped port (probe feed) and add an HFSS setup with a frequency sweep. .. rubric:: Examples Build a 5.8 GHz patch on a 0.787 mm Rogers RO4350B substrate: >>> edb = pyedb.Edb() >>> patch = RectangularPatch(edb_cell=edb, freq="5.8GHz", inset="4.2mm", layer="TOP", bottom_layer="GND") >>> patch.substrate.er = 3.66 >>> patch.substrate.tand = 0.0037 >>> patch.substrate.h = 0.000787 >>> patch.create() >>> edb.save_as("patch_5p8GHz.aedb") Probe-fed 2.4 GHz patch (no inset): >>> edb = pyedb.Edb() >>> RectangularPatch(edb, freq=2.4e9, inset=0).create() >>> edb.save_as("probe_patch_2p4GHz.aedb") :Attributes: **substrate** : :obj:`Substrate` Substrate definition (``er``, ``tand``, ``h``) used for all analytical calculations. .. !! processed by numpydoc !! .. py:currentmodule:: RectangularPatch Overview -------- .. tab-set:: .. tab-item:: Methods .. list-table:: :header-rows: 0 :widths: auto * - :py:attr:`~create` - Draw the patch, ground plane and feed geometry in EDB. .. tab-item:: Properties .. list-table:: :header-rows: 0 :widths: auto * - :py:attr:`~estimated_frequency` - Analytical resonance frequency (GHz) computed from the cavity model. * - :py:attr:`~width` - Patch width (m) derived for the target frequency. * - :py:attr:`~length` - Patch length (m) accounting for fringing fields. .. tab-item:: Attributes .. list-table:: :header-rows: 0 :widths: auto * - :py:attr:`~target_frequency` - * - :py:attr:`~length_feeding_line` - * - :py:attr:`~layer` - * - :py:attr:`~bottom_layer` - * - :py:attr:`~add_port` - * - :py:attr:`~substrate` - Import detail ------------- .. code-block:: python from pyedb.libraries.rf_libraries.planar_antennas import RectangularPatch Property detail --------------- .. py:property:: estimated_frequency :type: float Analytical resonance frequency (GHz) computed from the cavity model. :Returns: :class:`python:float` Resonant frequency in Hz. .. !! processed by numpydoc !! .. py:property:: width :type: float Patch width (m) derived for the target frequency. .. !! processed by numpydoc !! .. py:property:: length :type: float Patch length (m) accounting for fringing fields. .. !! processed by numpydoc !!
