This design could be used for any narrowband application that requires horizontal polarization
Besides, the current vectors show again that port 1 is responsible for vertical polarization, and port 2 contributes to the horizontal polarization
Again, we will first consider the horizontal polarization
case and the results obtained can be readily generalized to the vertical polarization case by exchanging "m" with "n" and "a" with "b" in the final analytical form obtained.
t_H(V)](D) denotes the extinction cross section of the raindrop with the diameter D illuminated by the horizontal polarization
wave (the vertical polarization wave), [[theta].
Let us now present the result for the horizontal polarization
2, rain influence into the radio wave propagation sharply increases in frequencies above 10 GHz and influence is higher in horizontal polarization
2004, 2006, 2008, 2009, 2010), the radar reflectivity factor at horizontal polarization
If we define V as vertical polarization and H as horizontal polarization
for the elements of the array, the mentioned four combinations are VV and HH (also called copolar polarizations) and HV and VH (also called crosspolar polarizations), as can be seen in Fig.
3, over a metallic ground plane is quasi hemispheric with horizontal polarization
in the broadside direction and vertical polarization at endfires.
The images are obtained by the passive MMW imaging system equipped with four-channel receivers operating in the 8 and 3 mm wavelength regimes with linear vertical and horizontal polarization
directions, thus the imaging system is capable of generating four images simultaneously.
Moreover, from Figure 2 it follows that the resonances for vertical polarization do not match in frequency with those observed for horizontal polarization
These procedures also require performing the tests with both vertical and horizontal polarization
Two orthogonal printed dipole antennas, each with a microstrip via-hole balun for vertical and horizontal polarization
, are combined and fabricated on a PCB substrate.
It is a unique antenna, highly suitable for challenging applications due to its high gain and horizontal polarization
Such photon pairs may both be vertically or horizontally polarized, or one photon may have a vertical polarization and the other a horizontal polarization
