Antenna Gain Calculator (dBi)
The dashboard presents the primary Antenna Gain calculation based on Directivity and Efficiency, along with associated Mismatch Loss metrics.
Primary Gain Calculation ($\eta \cdot D$)
Efficiency ($\eta$):
100%
Directivity ($D_{\text{dBi}}$):
0.00 $\text{dBi}$
Total Gain ($G_{\text{dBi}}$):
0.00 $\text{dBi}$
Mismatch Loss (VSWR) Metrics
VSWR ($\Gamma$):
1.0:1
Return Loss ($RL$):
- $\text{dBu}$
Mismatch Loss ($ML_{\text{dBi}}$):
0.00 $\text{dB}$
Enter the parameters below to determine the antenna's final gain and associated loss figures.
Primary Gain Parameters ($\eta \cdot D$)
Directivity is the gain assuming $100\%$ efficiency (no ohmic losses).
Represents power lost due to heat (ohmic losses). $100\%$ = 1.0.
VSWR Parameter (For Mismatch Loss)
The ratio of max to min voltage in the standing wave ($1.0$ is perfect match).
