Abstract :
This paper presents a new pattern synthesis algorithm with high radiation efficiency for the transmission antenna array. The synthesis algorithm uses adaptive array theory. By incorporating a quadratic constraint, the desired pattern characteristics, such as low sidelobe level, with high radiation efficiency can be achieved. With the sidelobe level fixed, a different value of Lagrangian multiplier corresponds to a different radiation efficiency.
