"""Creates a diode antenna (dantenna) structure.
This function generates a layout cell containing a rectangular antenna
region with optional recognition layers and guard ring structures.
Parameters allow customization of the antenna geometry and the type
and spacing of guard rings.
Args:
width: Width of the antenna rectangle in microns.
length: Length of the antenna rectangle in microns.
addRecLayer: Recognition layer to add (e.g., 't' for top, 'b' for bottom,
or '' for none).
guardRingType: Type of guard ring to include. Options include:
- 'none': No guard ring
- 'psub': P-type guard ring
guardRingDistance: Spacing between the antenna body and guard ring in microns.
Returns:
gdsfactory.Component: The generated antenna component.
