The ideal value of VSWR is 1 (one), which means that full power which has been arrived to the antenna is emitted to the air. In reality it is always more than 1, which means that some part of power reflected from antenna to the transmission line.
for an ideal matched transmission line, vswr is 1 and reflection coefficient is 0
VSWR is a ratio which represent the efficient performance in a radio emittion.
VSWR=Zo-ZL/Z0+ZL since open circuited ZL=infinity so VSWR=infinity
1.25:1
VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line = VSWR = Emax / Emin = Imax / Imin Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO
An ideal capacitor is characterized by a single constant value for its capacitance.
the voltage standing wave ratio is defined (1+p)/(1-p), where p is the the reflection coefficient magnitude. p = 1 for an open circuit, therefore the VSWR will approach infinite.
The motto of Ideal Jawa is 'Forever bike , Forever value'.

In an ideal DC power supply, there is no ripple.
