Microstrip loop antenna for wearable applications

This paper presents a microstrip rectangular loop antenna for wearable application. The substrate used for the prototype model is a FR4 material. The designed antenna can be integrated with a watch and is suitable for the wearable application. The characteristics of the prototype antenna developed, are measured in terms of the return loss, VSWR bandwidth, and radiation pattern. It is found that the fabricated antennas possess 210 MHz VSWR Bandwidth. This antenna can be placed over the outer ring a rectangular watch without disturbing the wearing comfort.
