Description

In order to support body-centric application cases, a new generation of antennas is
needed. When transmitters and receivers are placed in close proximity to one another on the body,
whether they are surgically implanted beneath the skin, directly linked to the skin, or
integrated into clothes, these antennas will play a crucial role in the resulting Body-Centric Wireless communication.

The several ways in which patch antennas are employed in the medical profession.
Research into on-body and in-body antennas, as well as current experimental results on
implantable and wearable antennas. Over the past decade, research into implanted and
wearable devices as a key area for wireless medical applications has increased
dramatically. These devices are utilized to offer crucial data like glucose levels,
blood pressure.

Using a wireless connection, the data may be sent from the implantable and wearable
antennas to devices located in the outside world given in figure 1.3. These antenna's
frequency response and radiation efficiency alter when it is placed in close proximity to lossy
human tissue, such as in a device worn by a person or an implanted device. One way to prevent
this is to use a body phantom during the design phase and to keep the antenna isolate
from the human body as feasible by using a ground plane to block electromagnetic
radiation. The entire system's efficiency will be preserved if the antenna
is built to withstand the near-field influences of the human body.
