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
The reflection coefficient is related to Voltage Standing Wave Ratio (VSWR) as follows: Reflection coefficient = (VSWR - 1) / (VSWR + 1) The reflection coefficient provides a measure of the strength of the reflected wave compared to the incident wave in a transmission line system.

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
British telecom is a old name of BT which deals in telecom and broadband
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.
To measure VSWR (Voltage Standing Wave Ratio) using a microwave bench setup, you would typically use a vector network analyzer (VNA). Connect the device under test to the VNA and measure the magnitude of the reflected and incident waves. The VSWR is then calculated as the ratio of these two values.
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.
