LOG-PERIODIC DIPOLE ARRAY ANTENNA |
摘要 |
According to an embodiment of the present invention, a log-periodic dipole antenna including a dielectric substrate; an emitter having multiple lines which extend from the center to the outer side, which are symmetrical to each other around the center on the dielectric substrate, which are alternately connected to each other at the center or in the outer side, and of which the length gradually increases from the top to which power is supplied to the bottom at a predetermined rate to resonate in first and second frequency bands; and a band rejection part at a point where the lines are connected to each other in order to reduce the gain of an antenna in a band between the first and second frequencies.
