MS Dielectric Resonator, Band Stop (MSDRBS)

Properties	Description	Units	Default	Range
W	Width of the microstrip	m	Required	> 0
D	Diameter of the dielectric resonator	m	Required	2mm < D < 100mm
HD	Height of the dielectric resonator	m	Required	(15×10^-5,0.1)
ER	Dielectric constant of the dielectric resonator	none	Required	[1,100]
S	Distance between dielectric resonator and microstrip	m	Required	[0,5×10^-2]
HT	Distance from cover plate to the top of the dielectric resonator	m	Required	> 0
HS	Standup height	m	0	[0,HD)
ES	Dielectric constant of standup layer	none	1	[1,ER]
L	Distance between the reference plane to the center of the dielectric resonator	m	Required	(0.5×D,0.1)
SDR	Conductivity of the Dielectric resonator	mho ´ m	10^-16	> 0
NM	number of modes	none	1	[1,10]
sub	Substrate name	none	Required	string

Notes

1. The following condition should be satisfied: 0.1 < D/HD < 10.

Netlist Form

MSDRBS:NAME n1 n2 D=val HD=val ER=val S=val HT=val [HS=val]
+ W=val L=val [SDR=val] [ES=val] [NM=val] SUB=label

Netlist Example

MSDRBS:DRBS1 1 2 HD=2.14mm D=6.02mm ER=36.2 HT=3.01mm S=0.3mm W=1mm L=50mm SDR=2mm SUB=SUB1

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