Question

For long distance radiation of an array antenna consisting of 5 Hertz dipoles located vertically at d=?/2 intervals along the Y-axis; (a) Subtract the expressions sequence factor (AF) and sequence pattern (pattern product). (b) Calculate the phases of the array elements to be fed in order to shift the radiation beam to the angle of ?0=90°, ?0=30°. (c) Suggest an appropriate method for suppressing the lateral lobe (ear) levels of the array radiation pattern.

Step 1

Step 1: Calculate the spacing between the dipoles Given that the dipoles are located vertically at d/2 intervals along the Y-axis, we can calculate the spacing between the dipoles using the formula: Spacing (d) = λ/2 where λ is the wavelength of the radiation. Show more…
