Let (31) be the relation between R and RFSR, where N [member of] (4, [infinity]), as (30) demands.
In Figure 11, it can be seen that during the discharge period, CFSR discharges through the paralleled resistances R and RFSR, which is very low and demands considerable amount of current.
The existence of D1 modifies the circuit in Figure 11 in a manner that CFSR is discharged only through RFSR and no longer the parallel between R and RFSR, as Figure 14 shows.
f = 1/ ((ln ((2R-2RFSR) / (4R-RFSR))) ((2R*RFSR) / (2R+ RFSR)) + ln (2)RFSR) CFSR, (35)
DC = (ln((2R-2RFSR)/(4R-RFSR)))((2R*RFSR)/(2R+RFSR)) / (ln((2R-2RFSR) / (4R- RFSR))) ((2R*RFSR) / (2R+RFSR)) + ln (2)RFSR, (36)
It is worth to remark that the presence of RFSR in the circuit cannot be neither eliminated nor diminished since this is a fundamental characteristic of FSRs.
(ii) RFSR influence: as (35) shows, even if R [much less than] RFSR, the dependence on RFSR still exists.
Hence, the RFSR structures reflect the incident waves back.
Consequently, the RFSR is reflective at 2.45 GHz and 5.25 GHz when the switch is OFF.
This antenna combines the corner reflector antenna and dual-band RFSR. Each dual-band RFSR can be controlled to be transmissive or reflective to waves at a designated frequency with only one switch.

The proposed dual-band pattern- reconfigurable antenna by the RFSRs. It consists of a dual-band feeding antenna in the center, four dual-band RFSRs on the side walls, and a finite-square ground plate on which the feeding antenna and RFSRs are perpendicularly mounted.
