Microstripline Fed Cylindrical Dielectric Resonator Antenna with a Coplanar Parasitic Strip
A coplanar parasitic strip loaded DRA has been presented in this paper. The antenna offers an impedance bandwidth of 17.33% at the center frequency of 2.77GHz and linear polarization of the radiation throughout the band. The wide impedance bandwidth is the result of dual radiating modes, which are excited in close vicinity as a result of the strip loading. Radiation patterns are found to be broad over the entire bandwidth with good cross-polarization levels. The possibility of shifting the operating band to the wireless application band is under investigation.
