Quoting from Electromagnetism By F.N.H.Robinson in the Oxford Physics Series 1973 edition ISBN 0 19 8518913 Chapter 11, Radiation, page 102 Formula 11.11 Has in the equation for radiated power the term (2*PI*L/LAMBDA)**2 where L is the antenna length and LAMBDA the wavelength, thereby showing that the radiated power decreases when the antenna length decreases. I will read up further and report further... Read this, Gareth: http://www.antenna-theory.com/basics/friis.php |
