Log periodic dipole array

A log periodic dipole array is a broadband high gain antenna. It has been used among other applications in electronic warfare.

The physical dimensions of a log periodic dipole array assembly are defined by its longest element length, shortest element length, scaling factor, spacing factor, radius or ratio and characteristic impedance, as shown in the dialog box below.
