La piu' semplice antenna, efficace ed economica e' il dipolo
Practical Dipole Antenna
A classic dipole antenna is 1/2-l long and fed at the center
Rilievo della carica e scarica del condensatore con il cronometro
L'obiettivo della esercitazione e' quello dello studio del transitorio di carica e scarica di un condensator
Roofspace Antennas
In designing the antenna, the first reqirement is to ensure that the section carrying the most current is a high as possible
Single-stub matching of transmission lines to loads
Impedance matching can be achieved by inserting another transmission line (stub) as shown in the diagram below
