Compact size of textile wearable antenna

The utilization of wearable antennas has rapidly developed in recent years for miniaturizing wireless communication devices. The main advantage of wearable antennas is that they are designed as clothing parts for transmitting or receiving wireless signals. The wearable antenna system plays an important role in many field applications, including tracking and navigation. This paper examines the performance of a rectangular microstrip antenna with different substrates/textiles. In addition, to significantly reduce the size of the antenna, the short circuit pins method has been proposed as part of the antenna design. With the proposed method, the antenna size has been reduced from 47.4 mm × 54.06 mm to 20 mm × 41 mm (approximate 68% area reduction).
