> Antenna Arrays - Volume 1 just released!
You can add this 344-page comprehensive book about antenna arrays now
either on CD or fast via download.
Antenna arrays are able to produce radiation patterns that combined, have
characteristics that a single antenna would not.
An antenna array is a group of radiators whose currents are of different
amplitudes and phases. They use electro-magnetic wave interference phenomena
to enhance the radiation signal in the desired direction and diminish it
in the non-desired direction. Antenna arrays are the solution to the problem
defined as the limitations of operating a single antenna. An example of
the problem! is that although a dipole antenna allows for better control of
direction than an isotropic (omni-directional) antenna — as the length of
the dipole increases, the control of direction decreases. Hence control by
changing the length of a single antenna is very limited. Greater flexibility
and control can be obtained for directing the beam with an arrangement of
multiple radiators.
