Analysis of AMC and EBG properties in Planar Log-Periodic Toothed Antenna

In this paper, the radiation performance of the log-periodic (LP)-toothed antenna to which the meta-reflector is applied using AMC and EBG properties are analyzed and compared. A four-arm LP-toothed antenna is designed for electronic support measures (ESM) with a meta-reflector. AMC and EBG characteristics are investigated through different cells and the antenna performance is compared. The frequency response of the radiation performance is analyzed through the field distribution analysis and a suitable characteristic as a meta-reflector of the LP antenna is suggested.
