Practical Antenna Basics - Making Sense of RF Propagation in Everyday Communications Systems

Bill Bailey  (Training Instructor, ETA International)

Location: N239

Date: Monday, March 27

Time: 9:00 am - 5:00 pm

Pass Type: ETA Training

Track: ETA International Training

Format: ETA Training

Vault Recording: TBD

This is a multi-day course that takes place on Monday and Tuesday.

In this course participants will be introduced to basic antenna theory. We will examine the fundamental principles of RF propagation and explore the antenna’s critical role in wireless communication systems. A major problem in any wireless communication system is the efficient transformation of internal circuit voltage and current into electromagnetic energy. Encoded and modulated with analog intelligence or digital data, electromagnetic radiation can then be propagated though space. The transformational complexity often results in an over-simplified explanation of an antenna as just a passive device with strange and magical abilities. Those attending this course will learn to dispel any mystical nature and develop a sound practical understanding of how antennas work. Topics addressed will include: the evolution of antenna theory (Maxwell’s equations, Faraday’s law, Ampere’s law, Marconi and Hertz); electrical to electromagnetic conversion (E and H field interaction, polarization, wave-fronts); characteristics of RF propagation (refraction, diffraction, fading, and travel path); half-wave dipole antenna development (effects of impedance, radiation and induction); antenna power ratios (dB’s and dBm’s); antenna performance (gain, directivity, reciprocity, radiation fields, beam-width, directionality); antenna feed lines (resonant and non-resonant); antenna design considerations (monopole antennas, antenna arrays, and electrical vs. physical length); specialized antennas (log-periodic, small-loop, folded di-pole, and slot antenna); microwave antennas (horn, parabolic reflector, lens and patch antennas); and common non-proprietary antenna installation, alignment, and maintenance practices. Upon successfully passing ETA’s antenna competency examination participants will be awarded ETA’s practical antenna basics (PAB) certification.
