The most popular antenna for portable devices in current communication
technologies is the wearable antenna due to its compactness and flexibility; demand
was rapidly growing and can communicate through signals with the human body and
the wearable devices. The advantages of wearable antennas are flexible, hidden, low
profile, and no harm to humans. The key benefit of this antenna is that it is placed on
the human body or included in clothing, effortlessly transmits, and receives signals
through clothes or on-body. These antennas play a vital role in the number of
applications, viz. navigation (118MHz to 137MHz), medicine (750MHz to 2.6GHz),
military (225MHz to 400MHz), RFID (433MHz to 5.4GHz), physical training,
tracking, and health monitoring, etc. This paper discussed the important aspects of
wearable antennas, which include materials used, substrate, and fabrication techniques.
Next, discussed a clear overview of wearable antennas existing and design aspects,
their advantages, and drawbacks.
