## Abstract A slot‐line‐excited equilateral‐triangular dielectric resonator antenna (DRA) of very high permittivity (ε~__r__~=82) is investigated experimentally. The triangular DRA is operated at its fundamental broadside __TM__~1, 0, −1~‐mode. An improved bandwidth of ∼5%, which is 1.7 times highe

Characteristics of a low-profile square-disk dielectric res-( ) onator DR antenna with a ¨ery high permitti¨ity excited by a coplanar ( ) wa¨eguide CPW are experimentally studied. The CPW is open circuited by a rectangular slot which also ser¨es a coupling slot for coupling the electromagnetic energ
## Abstract The radiation characteristics of a microstrip‐line‐excited rectangular dielectric resonator antenna (DRA) are studied experimentally. The radiation characteristics and excitation of different modes are highly influenced by the orientation of the DR, feed line parameters, and finite size
## Abstract A low‐profile equilateral‐triangular dielectric resonator antenna (DRA) of very high permittivity (ε~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
