Figure C-5: Radiation Pattern of Directional Antenna
Antenna Beamwidth
The directiveness of a directional antenna. Defined as the
angle between two half-power (-3 dB) points on either side of
the main lobe of radiation.
System Characteristics
Receiver Sensitivity
The minimum RF signal power level required at the input of
a receiver for certain performance (e.g. BER).
EIRP (Effective Isotropic Radiated Power)
The antenna transmitted power. Equal to the transmitted
output power minus cable loss plus the transmitting
antenna gain.
P
out
- Output power transmitted in dBm
Ct - Transmitter cable attenuation in dB
Gt - Transmitting antenna gain in dBi
Gr - Receiving antenna gain in dBi
