pcbStack
Single-feed or multifeed PCB antenna
Description
The pcbStack
object is a single-feed or multi-feed printed
circuit board (PCB) antenna. The pcbStack
object can be used
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 with Antenna Toolbox™ antenna catalog elements
To convert antenna array elements to PCB stack
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
sets
Properties using name-value pairs. For
example, pcbant
= pcbStack(Name,Value)pcbStack('FeedDiameter', 2.000e-04)
creates a
PCB antenna with a feed diameter of 2.000e-04 meters. You can specify
multiple name-value pairs. Enclose each property name in quotes creates a
PCB antenna, with additional properties specified by one or more name-value
pair arguments. Properties not specified retain their default values.
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 use antenna array objects from
the antenna array catalog elements them convert it into PCB antennas.pcbant
= pcbStack(ant)
