Abstract
In this work, different sizes and shapes of notched dielectric resonator antennas (DRAs) made of low-loss, high-permittivity ceramic are fabricated for broadband applications. Special-formulated glue is used to fabricate notched DRAs from different Zn3Nb2O8 parts. The sintered Zn3Nb2O8 parts are prepared by using Zn3Nb2O8 powder and small amount (∼0.1 wt%) of polyvinyl alcohol (PVA) which is imperative to have high densification and good dielectric properties of Zn3Nb2O8. The assembled DRA is fed through an aperture, which also serves as a slot antenna. The 10-dB bandwidth of the DRA is about 24%.
