Example Calculation
Suppose a lossless antenna has a radiation pattern given by:
Let us find the gain of such an antenna.
Solution:
First we find the peak radiation intensity of this antenna:
The total radiated power can be found by integrating over all directions:
Since the antenna is specified as being lossless the radiation efficiency is 1. The maximum gain is then equal to:
- .
Expressed relative to the gain of a dipole we would find:
- .
