The columns entitled αr refer to a directive pattern model with the relative lobe width.
The difference of level depends on the directive pattern of the used sensing element, here, the microstrip antenna.
A less parsimonious competing hypothesis would be that directive patterning was lost in three lineages (Rough/Eve, Mox, and anthox2) and then became restricted to a single side of the embryo in the Hox/ParaHox lineage.
We demonstrate that the oversteering technique applied to a weakly directive beam pattern can considerably increase the directivity, providing a frequency invariance that is better than those of traditional methods.
A directive scattering pattern model with scattering coefficient S = 0.4 and beamwidth α r = 4 has been chosen.
The first device is conceived to transform a directive radiation pattern into an isotropic one through a space-stretching.
In this paper, we employ a directive antenna pattern in [11], which can ensure more power radiated in the desired directions and decrease the power radiated towards undesired directions, on both the HAP and ground user.
In order to locate the source of the interference, a narrow directive radiation pattern can be shifted while monitoring SNR and traffic congestion metrics on the UL control channels, scanning this way the entire cell or sector.
Illuminated by radar signals, some targets, like metallic surfaces, have a very directive backscattering pattern or can be sensitive only to a singular frequency (anisotropic scatters or dihedral corner reflectors).
It is also worth pointing out that the approximations inherent in the FE procedure (notably in (11)) limit the extrapolation range and the quality of the corresponding super-directive beam patterns.
