This paper proposes a dual-band PIFA antenna operated at 28/38 GHz for 5G communication systems. The PIFA antenna consists of two dielectric layers and an air gap is inserted between these two layers. Both substrates, namely Roger RT dielectric, have a relative dielectric constant of 2.2 and a thickness of 0.127 mm.

In conclusion, the geotechnical properties of the unhydrated sand-mixed GBFS become more advantageous than those of natural sand. In addition, by mixing with natural sand, the hydration reaction rate and the solidification of GBFS are controlled. This means that it is possible to keep the compressive strength and the permeability at the predetermined conditions and, in turn, to satisfy requirements for the SCP method with LSRAR.

In this paper, we consider a nonlocal P -Laplace parabolic equation depending on the LP norm of the gradient with nonlinearity of arbitrary order. First, we prove the existence and uniqueness of weak solutions by combining the compactness and monotone methods and the weak convergence techniques in Orlicz spaces.

Two methods were proposed to calculate the thermodynamic parameters of porous ceramic compacts depending on their molar volume change with applied pressure and heating temperature, respectively. Molar volume of the porous α-alumina (α-Al 2 O3) compact was evaluated according to literature depending on both the applied pressure at room temperature and the heating temperature at atmospheric pressure. The isothermal compressibility coefficient, Gibbs energy, and work done on the compact by compression were calculated.
