Antenna and Array Fundamentals Training Part2
Antenna and Array Fundamentals Training Part2 Course Description
This two-day Antenna and Array Fundamentals Training Part2 teaches the basics of antenna and a brief overview of antenna arrays. 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 systems (transmit/receive) with active amplifiers are introduced. Finally, measurement techniques commonly used in anechoic chambers are outlined.
• Basic antenna concepts that pertain to all antennas and antenna arrays.
• The appropriate antenna for your application.
• Factors that affect antenna systems.
• Measurement techniques commonly used in anechoic chambers.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
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.
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.
