Improved Radiation Performance of Textile Antenna Using AMC Surface

This article focuses on the design, simulation and manufacturing of a miniaturized antenna operating in two 2.4 GHz and 5.8 GHz frequency bands for WLAN applications. This antenna is made using textile materials placed over an artificial magnetic conductor (AMC). The results of simulation and measurement are in good agreement and show that AMC can isolate the human body. AMC greatly improves the performance of the antenna. The realized gain of the antenna is 6.5 dB and 7.8 dB at 2.45 GHz and 5.2 GHz respectively (an increase of 4 dB compared to an antenna without AMC). The performance of the antenna on the human body is presented.
