N2 - Driven by the demand of low profile, wide bandwidth, high gain, and high radiation efficiency, dielectric patch antenna (DPA) has become an important innovation for antenna technology due to its limitless potential for futuristic applications. This article discusses all ceramic wideband DPA using high permittivity temperature-stable low-loss Ba4.5(Sm0.8La0.2)9Ti18O54 (BSLT) microwave dielectric ceramic prepared by solid-state reaction method at sintering temperature of 1380 °C. The fabricated ceramic has excellent microwave dielectric properties with permittivity (εr) (Formula presented.) 90.0, high Q × f value (Q = quality factor, f = resonant frequency) (Formula presented.) 8230 @ 3.54 GHz, and temperature coefficient of resonant frequency (TCF) (Formula presented.) +2.8 ppm °C−1. The main characteristic of designed DPA is its unique structure and design, where both patch and ground plane are made up of high εr, low loss, temperature-stable microwave dielectric ceramic. Wideband performance is realized by using air substrate and disk-loaded probe between ground and radiating patch. The fabricated DPA has wide bandwidth of 46.8% and measured realized gain of 6.5 dBi. Due to its excellent microwave properties and radiation performance, the proposed DPA is envisaged to have promising applications for 5G communication systems.
