Dielectric resonator antenna technology for wireless applications

This paper features some of the recent advances in dielectric resonator antenna technology at the Communications Research Centre, Ottawa, Canada. Several novel elements are presented offering significant enhancements to parameters such as impedance bandwidth, circular polarization bandwidth, gain, or coupling to feed structures. A variety of linear and planar arrays are also presented to illustrate the performance of these elements in an array environment. Dielectric resonator antenna technology offers a promising alternative to conventional antennas for wireless communication applications
