| Introduction: |
| |
This three-day course teaches the basics of antenna and antenna array theory. Fundamental concepts
such as beam patterns, radiation resistance, polarization, gain/directivity, aperture size, reciprocity, and matching
techniques are presented. Different types of antennas such as dipole, loop, patch, horn, dish, and helical antennas
are discussed and compared and contrasted from a performance/applications standpoint. The locations of the reactive
near-field, radiating near-field (Fresnel region), and far-field (Fraunhofer region) are described and the Friis
transmission formula is presented with worked examples. Propagation effects are presented.
Antenna arrays are discussed, and array factors for different types of distributions (e.g., uniform, binomial,
and Tschebyscheff arrays) are analyzed giving insight to sidelobe levels, null locations, and beam broadening (as
the array scans from broadside.) The end-fire condition is discussed. Beam steering is described using phase shifters
and true-time delay devices. Problems such as grating lobes, beam squint, quantization errors, and scan blindness
are presented. Antenna systems (transmit/receive) with active amplifiers are introduced. Finally, measurement techniques
commonly used in anechoic chambers are outlined. The textbook, Antenna Theory, Analysis & Design, is included
as well as a comprehensive set of course notes. |

| Audience: |
| |
| The standard presentation of this course assumes a bachelor of science in Electrical Engineering,
Mathematics, Physics, or a related subject along with some background in communications engineering. At least one
year experience in the field of communication engineering, fixed or wireless telephony, or related fields. |

| Customize it: |
| |
| This 3-4-day antennas course will be customized to your needs and specifications. Eno.com will
assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless
training. They will typically have a broad and general course, one size fits all, already developed and just put
your organization’s name on the title slide. This minimizes their effort and time investment. At Eno.com, every
course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really
need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit
you into our “standard”, one size fits all, class. |

| Course Aim: |
| |
|
After completing this course you will learn how to:
- Basic antenna concepts that pertain to all antennas and antenna arrays.
- The appropriate antenna for your application.
- Factors that affect antenna array designs and antenna systems.
- Measurement techniques commonly used in anechoic chambers.

| Course Outline |
| |
- Basic concepts in antenna theory. Beam patterns, radiation resistance, polarization, gain/directivity,
aperture size, reciprocity, and matching techniques.
- Locations. Reactive near-field, radiating near-field (Fresnel region), far-field (Fraunhofer
region) and the Friis transmission formula.
- Types of antennas. Dipole, loop, patch, horn, dish, and helical antennas are discussed,
compared, and contrasted from a performance/applications standpoint.
- Propagation effects. Direct, sky, and ground waves. Diffraction and scattering.
- Antenna arrays and array factors (e.g., uniform, binomial, and Tschebyscheff arrays).
- Scanning from broadside. Sidelobe levels, null locations, and beam broadening. The end-fire
condition. Problems such as grating lobes, beam squint, quantization errors, and scan blindness.
- Beam steering. Phase shifters and true-time delay devices. Some commonly used components
and delay devices (e.g., the Rotman lens) are compared.
- Measurement techniques used in anechoic chambers. Pattern measurements, polarization patterns,
gain comparison test, spinning dipole (for CP measurements). Items of concern relative to anechoic chambers such
as the quality of the absorbent material, quiet zone, and measurement errors. Compact, outdoor, and near-field
ranges.
- Questions and answers.
