Abstract :
An 8 beam planar phased array can transmit 8 signals in 8 different directions. The array is assumed to have 8 corporate feeds. The signal transmitted by a beam consists of the desired signal that is coherently combined from all the elements plus small amounts from the other 7 signals. These other signals distort the desired signal. This paper shows examples of these distortions.
