13 The basic of antenna input impedance and radiation resistance Input impedance Zi→If you see antenna as a circuit, it is circuit constant characteristics of antenna when you see antenna part from I/O port Zi=Rr+Rl+jX Radiation resistance Resistance loss reactance e.g. half-wave dipole antenna 73.13Ω As it gets bigger, heat loss will be increasing, and radiation efficiency of an antenna will be decreasing. Radiation efficiency = Rr Rr+Rl As Rr gets small, Rl cannot be ignored 2005/11/3
