Radiation resistance :
The radiation resistance of an antenna is defined as the equivalent resistance that would dissipate the same amount of power as is radiated by the antenna. For the elementary current element we have discussed so far. From equation (7.26) we find that radiated power density
Radiated power
| Fundamentals of Antennas and Radiating systems |
The maximum gain function is termed as gain of the antenna. Another parameter which incorporates the gain is effective isotropic radiated power or EIRP which is defined as the product of the input power and maximum gain or simply the gain. An antenna with a gain of 100 and input power of 1 W is equally effective as an antenna having a gain of 50 and input power 2 W. |
