Log Periodic Dipole Array Antenna

Calculate the radiation pattern and input impedance for a log periodic dipole array (LPDA) antenna. Non-radiating transmission lines are used to model the boom of the LPDA antenna.

The antenna operates at 46.29 MHz, with a wide operational bandwidth stretching from 35 MHz to 60 MHz.
