CPW-FED DUAL RECTANGULAR CERAMIC DIELECTRIC RESONATOR ANTENNAS WITH INDUCTIVELY COUPLED SLOTS

摘要

Coplanar waveguide-fed dual rectangular ceramic dielectric resonator antennas (DRAs) with inductively coupled slots are experimentally investigated, A double bandwidth is identified by comparing the antenna with a single dielectric resonator antenna (DRA). Input impedance can be easily matched by using various parameters, including the length of the inductive slots, the distance between dielectric resonators, and the offset distance from the center of the DR to the center of the inductive slots.
