Original Abstract

In the paper, we utilize Low Temperature Co-fired Ceramics (LTCC) as a dielectric material for design of a directive Dielectric Resonator Antenna (DRA). The antenna accomplishes its enhanced directivity by higher order modes excitation in relatively narrow frequency band. By using a slot in Substrate Integrated Waveguide (SIW) for feeding the resonator, the back radiation is significantly reduced as compared to microstrip feed line. The antenna produces broadside radiation pattern with linear polarization and radiation efficiency of about 87 %. The desired center frequency of the antenna is 25.5 GHz; however due to manufacturing tolerances, the resonant frequency of the fabricated antenna is shifted to 25.8 GHz.
