**Learning Objectives**

1. Define
the following terms: isotropic antenna, radiation intensity, gain, directivity,
radiation efficiency, effective area, polarization, radiation resistance,
bandwidth, radiation pattern, beamwidth, sidelobe level, aperture efficiency, and primary and
secondary patterns;

2. Given the
gain of an antenna and the power it accepts from a source, calculate the
radiated power density and the field intensities at a given distance and assess
potential hazards from radiation exposure. Derive the Friis
transmission formula and the radar formula;

3. Define
far field and determine the minimum distance for far-field conditions;

4. Given a
uniform linear array of antennas, calculate the progressive phase shift of
excitation to produce a main beam in a desired direction. State the principle
of pattern multiplication. Use it to find the radiation pattern of an array of
identical elements;

5. Describe
qualitatively the way in which equivalent sources are used to determine the
radiating characteristics of aperture-type antennas;

6. Given a
receiving system with individual gains and noise temperatures or noise figures,
estimate the overall noise temperature and noise power referred to the system
input.

7. Define
Fresnel zone clearance. Explain why a 4/3-earth-radius is used for profiling.
Describe qualitatively the effect of the earth's ionosphere;

8. Explain
qualitatively the operation of a wire antenna, a Yagi-Uda
array, a microstrip antenna, and a log-periodic
dipole array, and discuss their advantages and disadvantages;

9. Use basic
laboratory equipment to measure gains and radiation patterns of antennas;

10. Use a moment-method
numerical analysis program to model and analyze the fields from an antenna
system.
