This paper presents array antenna pattern synthesis with a fixed amplitude and limited phase range using genetic algorithm (GA). The array antenna can synthesize its pattern by controlling the amplitude and phase of each antenna element. However, a large phase shifter is required to control an arbitrary phase range of 360°. This proposed method can synthesize a cosecant squared beam (CSB) in the case of a 16-element, half-wavelength element spacing linear array with a fixed amplitude and limited phase range of less than 180°.
