Numerous therapeutic and light-based diagnostic devices are habitually used in the health centers. These devices are bulk in size, and they appear as items mounted on the wall. Recently, lot of research is undergoing to detect the diseases like cancer at its early stage. The above devices serve the purpose, but they seem to be large in size and bulky with wires. There is a need of device which is compact and simple. Wearable antennas serve this purpose. These antennas are capable of serving the medical needs. These wearable antennas are very useful to track the patient’s health and remotely monitor their condition. The user comfort for wearing this antenna is a crucial task. This paper reviews various wearable antennas used for medical fields and for commercial purpose. This includes textile antennas, non-textile antennas and patch antennas which work at a frequency of ISM band. Each of them having advantages and disadvantages which are highlighted in the review of the paper. Also keeping all these review essentials into note, a new antenna is designed which will resonate at a 2.45 GHz frequency along with metamaterial to reduce the surface currents which will affect when placed on a human body. The return loss is −15 dB, the gain is 2 dBi, and Voltage standing wave ratio is 1 as the resonant frequency is about 2.43 GHz.
