Abstract

The proposed Embroidery Wearable Snail Antenna (EWSA) is capable for dual-band operation which is 1.575 GHz for GPS application and 1.8 GHz for GSM application. The EWSA is basically designed in circle shape at the centre but then subtracted by square shape at the upper and bottom. In seeking good results, the optimization process is compulsory where the width of squares hold the key of dual band frequencies and good gain values. The gain produced is as high as 6.649 dB and 7.826 dB is obtained at the frequency of 1.575 GHz and 1.8 GHz correspondingly. Moreover, flexibility in structure enables the EWSA to be easily integrated into safety jackets and rain coats for tracking, search and rescue communication purposes.
