Cavity-Backed Slot Antenna Made of Flexible Material Fed from the Side Wall

Abstract (in Japanese) (See Japanese page) 
(in English) Antennas for shoe-mounted wearable devices operate in close proximity to high-permittivity objects such as the human body and the ground, which degrades their radiation characteristics. In this study, the radiation characteristics of a half-cylindrical cavity-backed slot antenna made of conductive textiles were evaluated in an environment sandwiched between dielectric materials representing the human body and the ground. To prevent an increase in antenna height caused by the feeding cable in the conventional structure, a new side-feeding structure was introduced. Measurement results showed that the proposed antenna exhibited no significant degradation in radiation characteristics even when sandwiched between dielectric materials, demonstrating its suitability for shoe-mounted wearable devices.
