title: Antenna Impedance Matching
author:  Wilfred N. Caron 
description: Antenna Impedance Matching is well written and matched to its target audience.  The use of graphs is excellent. The charts are helpful. The reader can learn to match an antenna using this book. Publications from the ARRL are always a bargain.

  Impedance Matching and the Smith Chart: The Fundamentals
  Tutorial on RF impedance matching using the Smith Chart. Examples are shown plotting reflection coefficients, 
  impedances and admittances. A sample matching network is designed at 60 MHz using graphical methods.
  Tried and true, the Smith chart is still the basic tool for determining transmission-line impedances. 
  When dealing with the practical implementation of RF applications, there are always some nightmarish tasks. 
  One is the need to match the different impedances of the interconnected blocks. Typically these include the 
  antenna to the low-noise amplifier (LNA), power-amplifier output (RFOUT) to the antenna, and LNA/VCO output 
  to mixer inputs. The matching task is required for a proper transfer of signal and energy from a "source" to a 
  "load."
