Abstract
In this paper, a wideband textile antenna for microwave imaging is presented. The antenna operates from 1.2 to 6 GHz at -10 dB level of the reflection coefficient magnitude. Whilst, the transmission coefficients of the two antennas are lower than -20 dB level. The SAR value when only one antenna is attached to the head phantom has been investigated. In addition, the maximum value of SAR is also obtained when two antennas are attached to the head phantom. The results show that the SAR levels are 0.047 W/kg and 0.022 W/kg at averaged 10 g tissues, respectively. Due to the values of SAR are far below the standard limit, thus this antenna is suitable to be used for microwave imaging.
