i design a 1*3 antenna array,for each element the gain in theta=36,phi=0 is1.63 without dB,but the total in this angle is 0.56,i think the total gain is The composition of these three vectors,If you take the vector of unit one as the reference vector,the result is 1.36+2vectors,i think it is larger than 1.36,but the arraygain is 0.56,i do not know why,can anyone tell me the reason

Phase plots of each may indicate degenerative gains of the aggregate array.

i don explain the question well before,i can not say that the value is large than1.63,because it is vector,my distant between elements is 0.86lambda,
i calculate the value is 1.66 far larger than 0.56,can you tell me the reasons,i think this could help me the make the calculation is conform to hfss simulation
