Antennas for wireless communication: recent advances using dielectric resonators

Over the last few years, developments in wireless communications have presented many challenges to the antenna and microwave communities in terms of special requirements for antenna design, fabrication and integration. These requirements include new characterisation in terms of antenna performance, miniaturised size and shape and new suitable fabrication and implementation techniques to fit with the devices. These aspects are addressed with a focus on recent developments in dielectric resonator antenna research to meet some of the new challenges. A few recent representative designs, which outline new innovations and improved antenna features, as well as directions for future research, are briefly described.
