Comparing the transmission characteristics of transmission lines.

Type	Mode	Bandwidth (GHz)	Fabrication	Loss	Size
RW	TE10	60–120 (66.7%)	Middle	Low	0.847  0.2
Ridge RW	TE10	53–123 (79.35%)	Low freq: middle; high freq: hard	Low	0.847   0.2 (ridge height 0.07 )
SRW	TE10	60–155 (88.4%)	Middle	Low	0.847   0.2
