The difference between the measured RSS and calculated RSS free space wave
propagation model was used as input-output data for the system identification.
(30)-(32), constitute the space wave
radiated by the antenna.
Similarly, with time fixed, [t.sub.0], one obtains a space wave
profile as a function of location x.
where the l is the length of aperture, a is the length of the strip line, K0 is free space wave
number and Zos is the characteristic impedance of coplanar strip transmission line which could be formulated as (3)
The formulas are also excellent for far-field (plane wave) calculations, where the free space wave
impedance is used.
where [DELTA]K is space wave
number difference of wave spectrum sample adjacent spectral domain, and N(0, 1) represents a Gaussian random variable that the mean is 0 and the variance is 1.
Major sources of the EM coupling are the surface wave, space wave
, and near- field coupling.
For many wireless applications in the 50 to 2000 MHz range, such as broadcasting, paging and mobile telephony, two components of the space wave
are of primary concern: energy received by means of the direct wave, which travels a direct path from the transmitter to the receiver, and the ground-reflected wave, which arrives at the receiver after being reflected from the surface of the earth.
On the other hand, the coupling between the driven and the reflector elements and that between the first and the second elements are through space wave
[k.sub.0z] is z-component of the free space wave
vector, and f([k.sub.x], z) is the Fourier transformed solution of wave equation in the inhomogeneous layer.
Such a dipole resembles an antenna radiating an electromagnetic wave that cannot be guided by the stripline and, thus, is emitted as a surface wave or space wave
The quasi fractional space is used in this analysis, because such a boundary was realized by Attiya , in which the magnetic field properties are equivalent to complementary fractional space wave
