Return loss of antenna object or scan return loss of array object, returned as a vector in dB. The return loss is calculated using the formula where, Z = input impedance of antenna or scan impedance of array Z0 = reference impedanceSee...
1.The Lichtenecher formula is used to culculate the electromagnetic parameters of radar absorbing coatings which are respectively made up of some adhesive and various radar-absorbing ingredients,thereflection lossformula (RLF) applicable to the homogeneous radar absorbing coatings is deduced according to ...
Return Loss in dB: It is a measure of reflected power back from a discontinuity (e.g. connector, impedance mismatch or component) in RF system. It is expressed in decibels (dB). Return loss formula is as follows. RL (dB) = - 20 * Log10(|Γ|) ...
Return Loss (dB)Mismatch Loss (dB) Loss in %Reflection Coefficient VSWR Reduction using a matched attenuator (assuming a perfect 1:1 Attenuator) Attenuator (dB)Improved VSWR Definitions: VSWR (Voltage Standing Wave Ratio)is the measure of how efficiently RF power is transmitted and is expressed ...
It is often necessary to convert between VSWR and return loss - this can be done using simple formulas or a table provided here.
You can calculate return loss when the VSWR is known. Many antenna specification sheets list the VSWR and some list the return loss, but many do not. When the VSWR is known, the return loss can be calculated as: Or in Excel, use the following formula: ...
Other interconnections share common sea electrodes, such as the two bipoles of Skagerrak 1 & 2 and Skagerrak 3 & 4, however in this case the loss of a single cable only results in the sea return carrying the current from one bipole [16]. The second exception is the New Zealand Inter-...
Return Lossis a amount of power that is lost to the load and returns back to the system as a reflection typically expressed in dB. A high return loss means more power is lost at the load. Loss in %is the percentage of power that is lost to the load and returns back to the system...
9. The method of claim 8, wherein said actual EIRP is calculated using a formula: EIRPi(θ)=L EIRPtG(θ)/Gt where “Gt” represents a transmit gain of the antenna to the space-based communications device; and “L” represents a loss term. 10. The method of claim 1, further compris...
The principal purpose of this section is to provide for a means of adjusting the output of the amplifier to compensate for cable characteristics through the use of a slope control. Cable characteristics can be calculated by the simple formula of . . . Cable Loss Ratio=square root of f1/f2×...
