Abstract
Broadband dielectric resonator antenna, formed by carving out notches from cylindrical geometry to form bowtie shape and fed by coaxial probe on one of the notched sides, is presented. The proposed broadband bowtie DRA combines shape deformation with low permittivity resonator to achieve impedance bandwidth of up to 49.4% covering frequency range of 4.194-6.944 GHz. The simulated and measured radiation patterns are consistent throughout the operational bandwidth.
