Abstract:
|
The author presents the development of a new dielectric resonator antenna(DRA) suitable for wideband wireless communication applications.The design comprises of a simple cylindrical dielectric resonator (DR) and a microstrip feed, in a low radiation-Q structure,enabling wide impedance bandwidth.The radiation pattern is conical shaped,resulted from thew low-Q structure.Dielectric constant of the DR,its dimensions and topological parameters of the feed line are the major design parameters of the antenna.By proper selection of these parameters,the DRA can be operated over a wideband width covering multiple wireless applications.The antenna is simulated using Ansoft HFSS TM and measured using HP 8510C vector network analyser.Some of the measured results are confirmed by using the Finite Difference Time Domain(FDTD) technique implemented in MATLAB. |
