Abstract: This paper manages scaling down and tuning of wearable electro-textile antennas by the utilization of Minkowski fractal geometries and tuning holes. Different electro-textile materials used for wearable electronics (like polyester fabric.) are considered for the substrate (or dielectric medium) configuration of microstrip antennas. In the essential outline these antennas are intended for WLAN applications and hence specifically tuned by tuning holes designed over the patch. The path antenna with tuning holes gives an increase of 3.2 dB with an impedance bandwidth of 150 MHz though, the change in material offers an addition of 3.4 dB and an impedance bandwidth of 162 MHz. By applying holes in Minkowski fractal geometry to the antennas, tuning is accomplished. Also the impact of different iterations are also considered to make them suitable for GSM 1900 applications. In these analysis, the performance and limitations of these designs in accordance with their separate operating environment are also compared. The reenactment studies uncover that tuning holes yields better results contrasted with normal antenna.
