2.1. An antenna has a beam solid angle that is equivalent to a trapezoidal patch (patch with 4 sides, 2 of which are parallel to each other) on the surface of a sphere of radius r. The angular space of the patch on the surface of the sphere extends between /6 ≤0 ≤/3(30° ≤ 0 ≤ 60°) in latitude and π/4 ≤ ¢ ≤ ñ/3(45° ≤ ¢ ≤ 60°) in longitude. Find the following: (a) Equivalent beam solid angle [which is equal to number of square radians/steradians or (degrees)²] of the patch [in square radians/steradians and in (degrees)²]. Exact. Approximate using = AO ·A= (0₂ – 0₁) · (₂ – Þ₁). Compare with the exact. (b) Corresponding antenna maximum directivities of part a (dimensionless and in dB).
