However, it is increased for vertical polarization
. The best cross-polarization levels achieved with or without image configuration for the probe-fed patch and aperture-coupled patch antennas at a maximum steering angle are compared, showing that the array of probe-fed patch antenna has a slightly better performance.
Since the microwave leakage is predominantly of vertical polarization
, in the event a coincidence of the spectral window of microwave leakage and a Bluetooth hopped-frequency spectrum takes place, a frame error could be anticipated only when the polarizations of both electromagnetic waves (of microwave leakage and the Bluetooth transmission) are identical.
The backscattered signature illustrates a null depth varying between 11 dB to 22.5 dB and from 7 dB to 16 dB for horizontal and vertical polarizations
Comparison of scattering coefficient between AIEM model and numerical results of MoM and SSA for both horizontal and vertical polarization
for a Gaussian correlated surface with [[epsilon].sub.r] = 4 - j1; [k.sub.[sigma]] = 0.5, k = 3.0, and incident angle of 30 degrees.
The vertical polarization
is obtained by ground waves up to 45[degrees] elevation angle while the horizontal polarization is obtained by NVIS propagation between 70[degrees] and 90[degrees] elevation angle.
Based on collocated SIBC, the FDTD models of lossy dielectric coatings on perfect conductors for parallel polarization and vertical polarization
plane wave at oblique incidence are developed in this article.
Computing results of vertical polarization
radio wave specific attenuation dependence from actual radio link frequencies, calculated for different rain rates are presented in Fig.
All models are dipole with a fundamental resonance of 1/4 wavelength and vertical polarization
. The range of motion is between a right angle or vertical (90[degrees] to 180[degrees]).
Both versions feature linear vertical polarization
and a [csc.sup.2] elevation pattern.
When the filter selects the polarizer or FSS, the polarization direction of transmitted feed at 183 GHz channel is rotated as horizontal polarization for reflection, and otherwise it is vertical polarization
for transmission at 324 GHz.
These results, obtained at 2.4 GHz, are presented in Tables 2 and 3, for horizontal and vertical polarization
respectively, whereas Tables 4 and 5 are related to 5.8 GHz experiences.
