Abstract

A dual band hybrid DR antenna consists of a CPW fed planar monopole and a circular-disk shape high permittivity dielectric resonator has been presented in this paper. The -10 dB S₁₁ bandwidth of the dual band hybrid antenna is 28 % and 11 % in the ISM band and UNNI band, respectively. The radiation in the ISM and UNNI band are due to the CPW fed planar monopole and circular-disk shape dielectric resonator, respectively. The radiation patterns in the x-z and y-z plane in the ISM and UNNI band are symmetrical about the broadside. The peak gains are about 5.17 dBi and 7.88 dBi in the ISM band and UNNI band, respectively.
