Embroidery Leaf Shape Dipole Antenna Performances and Characterisation

In this paper, leaf shape textile antenna in ISM band has been chosen to study. The operating frequency of the dipole antenna is 2.45GHz. The effect of conductive threads with three different types of sewing has been analysed. The first type of sewing leaf shape dipole antenna is to stitch around itself and embroidered into a fleece fabric with circular follow by vertical and horizontal stitch respectively. From measured return loss, the antenna with circular stitch shows better performances with optimum resonances compared with the two types of stitching. The measured results confirm that the circular stitch is more suitable for leaf shape dipole antenna design. Thus it can be concluded that different stitch gives different results for leaf shape dipole antenna

Leaf-shaped dual band antenna for wearable application

This paper presents the design of leaf shaped dual band flexible textile antenna. The textile antenna designed at 1.8GHz suitable for Long Term Evolution (LTE) and 2.8GHz WiMAX application. To enhance the flexibility of the proposed antenna and for the comfort of the user, denim textile is used as a substrate material. The conductive copper tape is used as the conducting element. The study also describes the energy coupled effect of two different sizes of leaf shaped to the antenna current distribution where it change the impedance and radiation characteristic of the antenna

Leaf-shaped dual band antenna textile performance for on-body application

A leaf-shaped dual band dipole textile antenna is proposed for on-body application. The antenna is designed to operate at Ultra High Frequency (UHF) range frequency at 1.8 GHz and 2.6 GHz. Denim substrate was used as the material due to its robustness, flexibility and lightweight. The antenna design is simulated, optimized and analyzed using Computer Simulation Technology (CST) Microwave Studio software and Voxel. Copper tape and ShieldIT fabric were used as conductive elements. Simulated result shows that the proposed antenna design meets the requirements of dual band antenna for on-body application. The proposed antenna is compact in size and flexible materials. Results in terms of return loss, bandwidth, radiation pattern, as well as gain are presented to validate the performance of the antenna
