Monostatic ultra-wideband GPR antenna for through wall detection

Abstract

Abstract. The aim of this paper is to present a monostatic arc-shaped ultra-wideband (UWB) printed monopole antenna system with 3-16 GHz frequency bandwidth suitable for through-wall detection. Ground penetrating radar (GPR) technique is used for detection with the gain of 6.2 dB achieved for the proposed antenna using defected ground structure (DGS) method. To serve the purpose, a simulation experiment of through-wall detection model is constructed which consists of a monostatic antenna act as transmitter and receiver, concrete wall and human skin model. The time domain reflection of obtained result is then analysed for target detection.

Ultra-Wideband Antenna with Monostatic/Bistatic Configurations for Search & Rescue Applications

“…Thereafter, a simulation-based experimental model for monostatic and bistatic antenna configuration is investigated to analyze the detection capability of the proposed antenna using CST-MWS environment. Basically the terms, monostatic refers to the configuration where only single antenna element can be used for transmission as well as the reception of signal by switching between the modes [8].…”

“…Based on the established study, this paper constitutes a simple design, and compact planar shape UWB arc antenna possess FR-4 based dielectric substrate. The acquired gain as well as the bandwidth for the proposed design is 6 dB and 13 GHz [8]. The design is derived with the well-known method called defected ground structure (DGS) [9] modified using current distribution concept.…”
