## Abstract A lowโprofile equilateralโtriangular dielectric resonator antenna (DRA) of very high permittivity (ฮต~r~ = 82) is excited with the use of a rectangular waveguide. It is found that the present configuration has a very wide impedance bandwidth of 11.4%, which is 3.8 times of that of the pr

## Abstract Hemispherical dielectric resonator (HDR) antenna excited with a slot at the short circuited end of waveguide is analyzed theoretically and verified experimentally. The analysis is based on numerical solution of coupled integral equations discretized using the method of moments (MoM). Th
Characteristics of a low-profile square-disk dielectric res-( ) onator DR antenna with a ยจery high permittiยจity excited by a coplanar ( ) waยจeguide CPW are experimentally studied. The CPW is open circuited by a rectangular slot which also serยจes a coupling slot for coupling the electromagnetic energ
