DESIGN AND ANALYSIS OF LOG PERIODIC DIPOLE ARRAY ANTENNA

Abstract
In this paper, Log Periodic Dipole Array Antenna is proposed for frequency range from 800MHz to 6GHz. Frequencies of interest for proposed antenna are CDMA (880MHz), GSM 900 (940MHz), GSM 1800 (1.84GHz), 3G (2.14GHz), 4G (2.35GHz), Wi-Fi (2.45GHz), Wi-Fi (5.1GHz), etc. The above are targeted frequencies because this antenna can be used for CDMA, 2G, 3G, 4G and Wi-Fi frequencies. Wideband log periodic antenna operating from 800MHz to 6GHz with 10 dipoles is designed, simulated on HFSS software and is realized on 1.6 mm Epoxy FR4 substrate. Designed antenna has advantages like wide bandwidth, simple design and the measured results are persistent with theoretical results. Antenna results indicate reflection coefficient below -10dB for whole band from 800MHz to 6GHz. The overall gain obtained is 4dB. This paper discusses complete idea about the LPDA and its design equations. Several parameters of antenna are evaluated and such antennas are used for applications like field strength meter.
