MS Radial Stub, Series, Aperture Width Specified (MSRSTW, MSRSTW_REF)

MS Radial Stub, Series, Aperture Width Specified (MSRSTW, MSRSTW_REF)

Schematic symbol MSRSTW

Schematic symbol MSRSTW_REF

Properties	Description	Units	Default	Range
A	Aperture angle	degree	Required	(0,300]
WI	Stub aperture width	m	Required	> 0
RL	Outer radius	m	Required	> (0.5WI) / sin(0.5A)
sub	Substrate name	none	Required	string
CoSimulator	Simulation engine	none		Planar EM
CoSimStackup	Stackup used for simulation	none	Layout Stackup	Layout Stackup, Footprint stackup, Substrate

Notes

1. Valid for H/l_g<< 1, where H is the substrate thickness defined in the corresponding .SUB statement, and l_g is the wavelength in the substrate.

2. The stub is open at the outer radius RL.

3. Conductor and dielectric losses are included if the metallization or the surface resistivity are specified with the substrate data.

Netlist Form

MSRSTW:NAME n1 [ n2 ] A=val WI=val RL=val SUB=label

Netlist Example

MSRSTW:1 1 A=60. WI=0.393mm RL=4.4mm SUB=SUB1

where sub1 needs to be defined in the corresponding .sub statement.
