The Trapezoidal Dielectric Resonator Antenna [PDF]
IEEE Transactions on Antennas and Propagation, 2008 The operational concepts of the trapezoidal dielectric resonator antennas (DRAs) are presented and their performance is studied theoretically and experimentally. The rectangular parallelepiped is a special case of the more general trapezoid and therefore a comparison between both is useful in order to highlight their similarities and differences. It is
