| dc.description.abstract | Wireless body area network contains sensors and actuators which work in the proximity of human body .For this purpose an antenna is needed which can work near the human body without any significant change in the bandwidth, gain and radiation efficiency of the antenna. This is a challenging task since it is observed that an antenna working near the human body faces shifts in the bandwidth, reduction in gain and radiation efficiency of the antenna. This is due to the fact that human body is lossy in nature and therefore most of the radiation is absorbed by the body resulting in very little gain and radiation efficiency. A rectangular patch antenna is designed on FR4 substrate and its characteristic is observed. To increase the bandwidth of the antenna the current path is changed by making proper slots on the antenna patch as well as ground plane. The characteristic of the antenna is observed for on body and free space conditions. When the antenna is loaded on human body a significant reduction in the radiation efficiency is observed. To mitigate this problem, an artificial magnetic conductor is used with the antenna. Antenna shows very good bandwidth for both on body and free space condition. With the AMC structure, the bandwidth of the antenna further increases. Also the radiation efficiency of the antenna with the AMC structure is good with very small back lobe radiation for both free space and on body condition. This shows the antenna is a good candidate for wearable application and WBAN. | en_US |
