True or False: Uniform antenna arrays are constructed of a number of identical radiating elements
True or False: The total electric field of an antenna array may be calculated by multiplying the radiated electric field of a single element located at the origin with the Array Factor (AF)
The Antenna Factor (AF) of an antenna array is dependent on which of the following factors?
True or False: A uniform linear array of antenna elements is capable of achieving higher directivity than is possible with a single one of its elements.
Find the magnitude of the array factor at $\theta=35^{\circ}$ for the two element uniform array shown, assuming $S = \frac{4\lambda}{5}$ and $\psi = 0^\circ$.
Find the magnitude of the array factor at $\theta=15^{\circ}$ for the two element uniform array shown, assuming $S = \frac{7\lambda}{9}$ and $\psi = 0^\circ$.
Find the magnitude of the array factor at $\theta=75^\circ$ for the 4 element uniform array evenly distributed along the z axis shown below, assuming $S=\frac{3\lambda}{2}$ and $\psi = 0^\circ$.
Find the magnitude of the array factor at $\theta=30^\circ$ for the 4 element uniform array evenly distributed along the z axis shown below, assuming $S=\frac{7\lambda}{4}$.
Choose the angle at which a null occurs in the radiation pattern for the antenna array shown below, assuming $S=\frac{3\lambda}{5}$ and $\phi = 0^\circ$.
Choose the angle where a null occurs in the radiation pattern for the antenna array shown below, assuming $S=\frac{7\lambda}{8}$ and $\psi = 0^\circ$.
