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.
Highlights
Ultra-wideband (UWB) is a wireless technology, which is mainly referred to a system with very larger operating bandwidth, usually this bandwidth is considered to be greater than 500 MHz
Such advantages widen the number of prominent applications in the field of communications such as wireless local area network (WLAN), wireless body area network (WBAN), WiMAX, wireless personal area network (WPAN), in the field of radar like ground penetrating radars (GPR), imaging and positioning [3]
For the implementation of UWB technology in the applications of GPR different types of antenna like a horn, bow tie, tapered slot, patch, spiral, and dipole antennas have been designed previously. These type of antennas are considered for their high gain, design complexity, directivity and frequency bandwidth which are the basic requirements in antenna design for GPR applications [7
Summary
Ultra-wideband (UWB) is a wireless technology, which is mainly referred to a system with very larger operating bandwidth, usually this bandwidth is considered to be greater than 500 MHz. UWB covers the frequency band ranges from 3.110.6 GHz with 7.5 GHz bandwidth, there are several advantages of this very large bandwidth as it consumes less power, have low implementation cost, with high data rate and time-resolution, have the capability of obstacle penetration [2] Such advantages widen the number of prominent applications in the field of communications such as wireless local area network (WLAN), wireless body area network (WBAN), WiMAX, wireless personal area network (WPAN), in the field of radar like ground penetrating radars (GPR), imaging and positioning [3]. For the implementation of UWB technology in the applications of GPR different types of antenna like a horn, bow tie, tapered slot, patch, spiral, and dipole antennas have been designed previously These type of antennas are considered for their high gain, design complexity, directivity and frequency bandwidth which are the basic requirements in antenna design for GPR applications [7-
