Abstract
A dielectric resonator antenna of triangle shape is examined numerically and experimentally. The geometry is an equilateral triangular dielectric volume over a ground plane, and is excited by a coaxial probe to provide a broadside radiation pattern. An approximate expression is used to compute the resonance frequency. Results are verified experimentally and numerically.βΒ© 2001 John Wiley & Sons, Inc.

The characteristics of the dielectric resonator antenna top loaded by a circular conducting disk with different diameters is studied experimentally. It is found that antenna parameters such as the resonant frequency, the input impedance, and the far-field radiation pattern, are affected tremendously

## Abstract A lowβprofile equilateralβtriangular dielectric resonator antenna (DRA) of very high permittivity (Ξ΅~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
laser (EXFO FLS2600). The transmitted optical power is measured with a powermeter (HP 81532A), working in the 800 -1700-nm range. Both the optical source and detector are connected to a computer by GPIB links. By varying the wavelength of the tunable source laser and measuring the transmitted power,
