1. A CW circularly polarized uniform plane wave is traveling in the +z direction. Find the polarization loss factor PLF (dimensionless and in dB) assuming the receiving antenna (in its transmitting mode) is

a. CW circularly polarized b. CCW circularly polarized

ECE307 – Antenna Engineering Section E1011 (Set – 02)

1. The normalized radiation intensity of a given antenna is given by by U = sin θ sin3 φ.

The intensity exists only in the 0 ≤ θ ≤ π, 0 ≤ φ ≤ π region, and it is zero elsewhere. Find the

a. exact directivity (dimensionless and in dB). b. azimuthal and elevation plane half-power beamwidths (in degrees).
