Abstract :
A grid array antenna (GAA) printed on a dielectric substrate is investigated to obtain dual-beam radiation. For the analysis of the GAA, the method of moments (MoM) is applied to an integral equation expressed by Sommerfeld-type integrals. It is revealed that the maximum beam direction, gain, and half-power beam width in the principal plane are changed with frequency. The dual-beam radiation is obtained, if the operating frequency is appropriately chosen.
