4. Describe Hertzian dipole and magnetic dipole and explain the difference between them. 5. A cone is centered on the positive z-axis with its vertex at the origin. The cone angle in spherical coordinates is ${?}_1$. a. If the cone is subtends 1 sr of the solid angle, determine ${?}_1$. b. If ${?}_1={45}^{?}$, find the solid angle subtended. Answers: a. $32.8^o,?\sqrt{2}$ 6. Evaluate the percentage of the maximum power density that is found in the direction $?={45}^{\mathbf{o}}$ for dipole antennas of overall length: a. ${}^{?}/4$ b. ${}^{?}/2$ C. $?$ Answers: a. $45.7\%$, b. $38.6\%$, c. $3.7\%$
