Textile Yagi antenna at 1.8 GHz

In this work, a textile Yagi antenna on jeans fabric is designed, simulated and tested. The proposed textile antenna operates at the digital cellular service band (DCS 1800 MHz) and it has been designed by means of the commercial full 3D electromagnetic CST Microwave Studio simulator. The textile antenna under test presents a gain range from 6.32 dBi to 7.26 dBi, with radiation efficiency from 90.52% to 91.34%, respectively. The results demonstrate the feasibility to use textile Yagi antenna on RF energy harvesting applications.
