A Multi Stub Polygon Shaped Textile Antenna for Deformation Performance Using Aperiodic DGS

A compact fully flexible antenna with 1.22 as dielectric constant 0.016 loss tangent is designed for wearable biomedical applications. It has dimensions of 40.5 x 23 0.97 mm3. The polygon-shaped patch modified to achieve ultra-wideband frequencies using partial ground 16.5mm and a periodic vertical slot 13x2 mm2 structure in defected enhance the wide bandwidth 2.6-11.1 GHz. Using transmission line equation microstrip feeding method, resulting operates at frequency open space on body-worn case multi band i.e. 3.1 5GHz. deformation process works well proposed without affecting its actual 20 60 mm radii. Additionally, 5GHz Wi-Fi 3.67dBi gain, -35.1dB S11 which suitable commercial CST Microwave Studio was used simulate fabricate it testing.
