- MONOPOLE-TYPE LOG-PERIODIC LOOP ANTENNAS WITH A GROUND REFLECTOR FOR MOBILE COMMUNICATIONS

摘要

The present invention relates to a log-periodic multiloop antenna having a ground reflector and a monopole for mobile communication to increase mobile communication performance. According to one embodiment of the present invention, the log-periodic multiloop antenna comprises: a loop radiating unit in which a plurality of loop element antennas including a first loop element and a second loop element are periodically arranged; a feeding unit connected to the first loop element; a ground reflection unit positioned below the first loop element and formed into a ground plane; and a fixing unit positioned on the central axis of the loop radiating unit and formed to penetrate the ground reflection unit.
