A novel miniaturized ultra wideband log-periodic antenna

Abstract: The log-periodical antenna (LPDA) is a kind of ultraw wide-band antennas. To achieve the purpose of miniaturization of the LPDA in radiate direction, this paper presents a novel structure log-periodically loaded with symmetrical meandering dipoles. The radiate direction is reduced to 46% of the conventional LDPA. The return loss is less than -10dB from 200MHz to 2GHz, according to the simulation results. A good directivity is also obtained that the gain ranges from 1.9dB to 7.2dB.
