Magneto-dielectric substrate influence on the efficiency of a reconfigurable patch antenna

Analysis of the effect of dielectric losses on the bandwidth of microstrip patch antenna in stacked geometry and modelling

“…In [14], the negative effect, on the radiation efficiency of both the magnetic loss tangent and the dielectric loss tangent, is investigated, in single-layer rectangular patch geometry using full-wave simulations, where they show positive impact on the antenna bandwidth.…”

“…Although extensive research has been carried out on losses within dielectric materials, the investigation of dielectric losses effect on MPA performance beyond the single-layer geometry, using alternative full-wave method, is crucially important. The stacked patches antenna geometry is considered to be more general compared to the single-layer geometries as in [14][15][16][17], where the three different geometries are possible: simple patch geometry, superstrate geometry, and stacked patch geometry.…”

“…This work focuses on modeling and analyzing losses within nonmagnetic dielectric materials ( r = 1 ) in stacked patch geometry, which they have low cost compared to the magnetodielectric materials [14][15][16][17]. The effect of dielectric losses on both lower and upper bandwidths, as well as on quality factors, is investigated in this paper.…”
