| الوصف: | International audience ; This paper presents the integration of a dielec. La$_2$Ti$_2$O$_7$ compd. as thin film in a discrete capacitive component operating at microwaves. The integration in a notch antenna of a MIM (metal/insulator/metal) structure based on this oxide material is numerically and exptl. studied. Oxide films are deposited by reactive magnetron r.f. sputtering of anLa$_2$Ti$_2$O$_7$ target. The films are composed of an unusual phase: the orthorhombic La$_2$Ti$_2$O$_7$ compd., with a textured growth on Pt/Si and Pt/SrTiO$_3$ substrates. Moderate dielec. const. values (Epsilon around 60) and low loss (tan Delta lower than 0.005) are obtained at 1 GHz. Inserting this original MIM capacitor in the antenna structure results in a shift to a lower value of its operating frequency. This shift, from 885-317 MHz, corresponds to a significant size redn. of 64.2%. The measured values are confronted with simulation obtained by numerical software. |
