Antenna Gain

A theorem about cats:
Antenna are directional
An isotropic antenna can not exist.

 

 

Antenna Gain

GT (f,q) is the amount of power radiated in direction (f,q), relative to an isotropic antenna.

 

 

Definition: Effective Radiated Power (ERP) is PT GT

 

 

Half-Wave Dipole: A half wave dipole has antenna gain
