Abstract :
The radiation characteristics of a grid array antenna for one-line excitation are investigated using the method of moments. This grid radiates a dual-beam. It is revealed that the co-polarized electric field components are the same in the two principal planes. The direction of maximum radiation and the gain are discussed.
