In this paper, ferroelectric ceramics with (Sr2Ta2O7)100−x(La2Ti2O7)x (STLTO) compositions have been investigated and their dielectric properties have been characterized in wide frequency band (from few kHz to few GHz); their integration in Dielectric Resonator Antennas (DRA) was conducted. The dense STLTO ceramics have been obtained by high temperature sintering of powders synthetized by solid state chemistry route. STLTO crystalline cell parameters and volume vary linearly as a function of the chemical composition (x) thus demonstrating an ideal solid solution domain for 0 ≤ x ≤ 3. Dielectric characterizations highlight that the permittivity and the dielectric loss vary according to the composition (x) and that the lowest losses are obtained for x<1.65 compositions. The latter corresponds to the transition between the ferroelectric and paraelectric compositions of the STLTO material at room temperature. A low profile DRA structure was realized using a cylindrical paraelectric STLTO resonator (with x = 0) with a permittivity of 83 and losses tanδ = 5 × 10−3@3.3 GHz. The DRA prototype was simulated, produced and tested. It exhibits a hybrid HEM11δ mode, with a resonant frequency at 5.80 GHz, a 4.9% bandwidth and a gain of 6.4 dB.
