Effect of Ground Plane Dimensions on the Performance of Wearable Jeans Antenna

Nowadays, textile antennas are quite popular and used in many applications like body wear, health parameter monitoring, wireless communication, etc. In textile antennas, mostly non-conducting fabric is used as a substrate, and conducting fabric is preferred for radiating patches. This paper includes an antenna made of jeans substrate, and copper is used for the conducting patch. For antenna design, patch dimensions of 47.74 x 46 mm and substrate dimensions of 62 x 60 mm are used. An antenna is simulated using high frequency structure simulator. The antenna operates at a 2.4 GHz frequency. If there is a change in ground plane size, then the effect on operating frequency, VSWR, gain, and directivity of the antenna is observed here. Gain improvement takes place when ground plane length is long and improvement in resonant frequency is obtained when ground plane length is decreased.
