Bandwidth Reconfigurable Metamaterial Arrays

Table 2

MTM array performance for various choices of the load termination of the open stub.

Chosen state	SW1	𝐶1	𝐿1	𝐶2	𝐿2	Configuration	Bandwidth (%)	Bandwidth (MHz)
1	X				X	high Pass	9.3	400
2	X			X		low Pass	58	515
3	X			X	X	bandpass	53	1,300
4		X	X			band-stop	22*	565*
5	unconfigured					UWB	161	3,960

X = activated (on)/closed switch; no marker = deactivated (off)/open switch.
Bandwidth is listed for VSWR < 3; *indicates band rejection bandwidth.
𝐶₁ = 3 pF, 𝐿₁ = 1.3 nH, 𝐶₂ = 1.75 pF, and 𝐿₂ = 2.5 nH.
All other MTM array circuit parameters are given in Figure 20.
