pcbStack
Single feed or multi-feed PCB antenna
Description
The pcbStack
object is a single feed or multi-feed printed
circuit board (PCB) antenna. Use the pcbStack
object:
To create single-layer, multilayer metal, or metal-dielectric substrate antennas.
To create an arbitrary number of feeds and vias in an antenna.
To create a PCB antenna from antenna and array catalog elements.
Note
To generate a Gerber file, a substrate layer is required. Use the
Substrate
property to create this layer in the PCB antenna.

Creation
Description
creates an
air-filled single-feed PCB with two metal layers.pcbant
= pcbStack
creates a PCB antenna, with additional Properties specified by one or more name-value
arguments. pcbant
= pcbStack(Name=Value)Name
is the property name and
Value
is the corresponding value. You can specify
multiple name-value arguments in any order as
Name1
=Value1
,
...
,
NameN
=ValueN
. Properties not
specified retain their default values.
For example, pcbStack(FeedDiameter=2.000e-04)
creates a
PCB antenna with a feed diameter of 2.000e-04 meters.
converts
any 2-D or 2.5-D antenna from the antenna catalog into a PCB antenna for
further modeling and analysis. You can also convert antenna array objects
from the antenna array catalog to a PCB antenna. For a list of supported
catalog elements, see Supported Catalog Elements.pcbant
= pcbStack(ant)
