The antennas which are designed in a manner to operate when they are worn or textile fabricated is entitled as Wearable antennas. In recent communication trends like Internet of Things (IOT) these wearable antennas engage themselves in decisive roles where the data connectivity between smart devices is made achievable across the world. They can be worn by fabricating it in any textile material and the demand for wearable antennas are increasing widely in the areas like Medical applications, smart gadgets, remote monitoring and Defense applications. The antenna designated for wearable application should posses the characteristics like size compatibility, low specific absorption rate (SAR), better efficiency, flexibility to withstand the bending and twisting effect in the fabric. Antenna should also be able to survive the loss due to near field effect of human body since they act as a lossy material which absorbs energy from electromagnetic waves resulting in large reduction of antenna efficiency. Microstrip antenna is one of the best suited antennas for the above mentioned requirement since it is easy to fabricate in the textile material, conformal in nature and can be hidden in the clothing. This paper is broadly arranged into three categories which describes about the requirements of wearable antennas, study of substrate characteristics and review of different substrate materials used in microstrip antenna which can be used in wearable application.
