dc.description.abstractA broadband Dielectric Resonator Antenna (DRA) is an antenna that can transmits and receives electromagnetic signals over a wide range of frequencies in high-capacity telecommunications. Dielectric materials with low permittivity and low quality factor can store relatively less electromagnetic energy and hence suffers from weak coupling to the excitation source. On the other hand high permittivity materials have high quality factor and strong electric and magnetic fields can be formed inside resonator, hence can operate in a narrower bandwidth with strong coupling. In order to have a strong electromagnetically coupled dielectric resonator antenna which can be operated in wider range of frequencies, two different permittivity materials are used to design the antenna. Rectangular shape dielectric material is used as a resonator for both segments of DRA because mode degeneracy can be controlled by choosing appropriate aspect ratios of the resonators. For top segment of the resonator a dielectric microwave laminate Rogers RT 6010 from Rogers Corporation is used as principle resonator. For bottom segment, which acts as an impedance transformer, between top segment and feed line, two different dielectric materials i.e. Barium Zinc Tantalum (BZT) and Calcium Copper Titanate (CCTO) were fabricated. For single element antenna and two element array antenna BZT is used as transformer while for four element and eight elements array CCTO were used to have control over mutual coupling between immediate resonators.en_US
