The role of the antenna is to match circuit/air impedances. Without the
antenna the signal cannot propagate out of the circuit and is reected back,
and the antenna impedance matches the transmitter output impedance
(Figure6.31).
6.9.3 Maximum Voltage or Current Transfer
Here we will consider the conditions we must satisfy to transfer the maximum volt-
age value from the source to the load, realizing what is referred to as impedance
bridging, since it is a bridging connection if the Z
L
device does not appreciably
load the Z
S
component, so that no power is transferred.
An example of impedance bridging comes from the audio ampli ...
