Summary: This paper proposes a compact and conformal wearable antenna made of textile material for the 2.45 GHz ISM band. The design consists of a monopole radiator and a 2 x 1 Electromagnetic Band Gap (EBG) array, which results in a small form factor suitable for wristband applications. The EBG unit cell is optimized for the desired operating band, and the monopole radiator works in association with the EBG layer to produce resonance in the ISM band. The experimental results show that the antenna design achieves a bandwidth of 2.39 GHz to 2.54 GHz with a compact size of 35.4 x 82.4 mm(2), and it remains effective even in close proximity to the human body.

Summary: This article proposes a novel methodology to create metallic waveguides with a multilayer integrated vertical-electromagnetic bandgap (EBG) structure, achieving low-cost millimeter-wave (mmWave) slot array antennas. By using a stack of easy-to-process thin metallic etching plates instead of diffusion bonding and welding assembly process, the mmWave waveguide can be designed. The electromagnetic wave leakage between the metallic plates is suppressed using the vertical-EBG structure and antiphasing feeding. The design concept is verified through the presentation of two examples of slot array antennas.

Summary: A multiconductor transmission-line (MTL) model is proposed to model the uniplanar compact electromagnetic bandgap structure (UC-EBG). The model is based on a 2-D arrangement of metamaterial-based electromagnetic bandgap structures (MTM-EBGs). The dispersion properties and miniaturization potential of the UC-EBG unit cell are analyzed, and it is shown that the MTL model offers a recipe for highly miniaturized UC-EBG unit cells that can be integrated into printed circuit board (PCB) systems.

Summary: The development of on-body antennas has become increasingly important in wireless technology, particularly for applications that require close contact with the human body. These antennas outperform normal antennas and have characteristics such as flexibility, reflection coefficient, bandwidth, directivity, gain, radiation, specific absorption rate (SAR), and efficiency. Improvements like band-gap structure and artificial magnetic conductors (AMC) and (DGS) have been incorporated to provide isolation from the human body and reduce SAR.
