2.43. A circularly polarized wave, traveling in the positive z-direction, is received by an ellipti-
cally polarized antenna whose reception characteristics near the main lobe are given approx-
imately by
E_(a)≃[2hat(a)_(x)+jhat(a)_(y)]f(r,\theta ,\phi )dB E_(a)≃[2hat(a)_(x)-jhat(a)_(y)]f(r,\theta ,\phi )
In each case, what is the polarization of the antenna? How does it match with that of
the wave?
