SMALL LOG-PERIODIC DIPOLE ARRAY ANTENNA

摘要

PURPOSE: A small log-periodic dipole array antenna is provided with a minimum size in order to prevent gain turn-down. CONSTITUTION: A parallel transmission line (10) comprises a regular length. The parallel transmission line comprises first and second transmission lines (10a, 10b). A plurality of dipole elements faces to each other around the first and second transmission lines. The plurality of dipole elements comprises meander dipole elements (20) and linear dipoles (30). The meander dipole elements are formed into two triangle shapes around the parallel transmission line.
