201 A two-element dipole array is configured to provide zero radiation in the broadside (4 =+ 90°) and endfire ( = 0, 180°) directions, but with maxima occurring at angles in between. Consider such a setup with w = x at o = 0 and y = -3z at o = 1, with both values determined in the H plane. (a) Verify that these values give zero broadside and endfire radiation. (b) Determine the required relative current phase, 5. (c) Determine the required element spacing, d. (d) Determine the values of o at which maxima in the radiation pattern occur.
