A wake-up receiver with ad-hoc antenna co-design for wearable applications

Body Area Networks (BAN) have received significant attention in recent years and have found a wide range of applications, including wearable devices for fitness and health tracking, and mobile communications. Battery lifetime continues to be the main …

Bandwidth enhancement of rectangular dielectric resonator antenna for UMTS application

A novel wideband rectangular dielectric resonator antenna (RDRA) is proposed in this paper. An equivalent air-dielectric DRs blocs are introduced inside the resonator to enhance the structure's bandwidth. The hybrid structure is excited by a simple …
