Reconfigurable Metal Chassis Antenna
IEICE Transactions on Communications, 2019 Smartphones for wireless communication typically consist of a large area frontal liquid crystal display (LCD), which incorporates a metal back plate, and a back cover chassis made from metal. Leveraging this structure a new approach to construct antennas for smartphones is proposed where the complete metal back cover chassis and LCD back plate are used

Reconfigurable water antennas [PDF]
2014 IEEE Conference on Antenna Measurements & Applications (CAMA), 2014 This paper introduces two types of reconfigurable water antennas. One is a water-grating leaky-wave antenna and the other is a sea-water monopole antenna. The water-grating leaky-wave antenna consists of a parabolic reflecting surface-wave launcher and a periodic water-grating structure, which is designed for wide-angle beam-scanning.
