Dual linearly polarized X-band dielectric resonator antenna yielding symmetric radiation patterns

Abstract : A dielectric resonator antenna is excited by two orthogonal H-shaped aperture slots yielding two orthogonal polarizations in the broadside direction. A common impedance bandwidth of 5.9% and input port isolation of -35 dB are obtained in the X-band. The broadside radiation patterns are found to be highly symmetric and stable with cross polarization levels -15 dB or better over the entire matching frequency band. The maximum measured gain is found to be 2.5 dBi at 8.4 GHz. (c) 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:9991001, 2012; View this article online at wileyonlinelibrary.com.
