antenna radiation การใช้

As one moves around, one gets a feel for the antenna radiation pattern.
This leads directly to the earlier stated maximum gain relation to a dipole by the definition of gain a G = \ epsilon D where \ epsilon is the antenna radiation efficiency.
The beam solid angle, represented as \ Omega _ A, is defined as the solid angle which all power would flow through if the antenna radiation intensity were constant at its maximal value.
A user ( Mr . PIM ) has eliminated link from the Side lobes article to the related section in the German article on antenna radiation pattern ( : de : Antennendiagramm # Nebenkeulen ).
For example, for axial-fed dish antennas, the antenna boresight is the axis of symmetry of the parabolic dish, and the antenna radiation pattern ( the main lobe ) is symmetrical about the boresight axis.
