An engineer is seeing a pattern closest to that of an Isotropic Radiator. What other antenna will produce a similar pattern?
A. 5 dBi patch
B. 13.5 dBi Yagi
C. 2.2 dBi omni
D. 21 dBi parabolic

C. 2.2 dBi omni
D. 21 dBi parabolic
Answer should be D since omni antennas provide coverage in a doughnut-like shape which is very different from the Yagi shape. A parabolic antenna is more similar to a Yagi pattern.
The question is asking which antenna type is most like the radiation pattern if the imaginary perfect isotropic antenna. When drawn from the H-plane, it would be a perfect circle. Only the omni antenna would be anywhere close to that since it radiates in all directions. The answer is C.
