The output of a three element co-linear antenna array operating in a free space environment is combined after appropriate phase shifting) to maximize the signal received from a particular direction as shown in figure
If the inter-element spacing is half of the signal wavelength and the direction of maximum response is $$30^\circ$$ from line perpendicular to the array ,what are the phases to be apllied to the each element? Consider the first element as the reference?
