Further details can be obtained from CPMAS experiments performed at two different cross-polarization
A broadband two-layer shorted patch antenna with low cross-polarization
is presented by Baligar .
The slotted waveguide array antennas have been used extensively for EO instrument application since they exhibit interesting performances such as high antenna gain efficiency low cross-polarization
They cover in-phase and quadrature impairment and compensation techniques, nonlinear power amplifier linearization, radio-frequency in-band distortion compensation, array calibration for digital beamforming applications, cross-polarization
interference cancellation in dual-polarization communication systems, and carrier frequency offset and phase noise mitigation.
He further explained that despite it being an absolute speculation, if one looks at what Apple wants to accomplish with its mobile market and Microsoft's initiative, there is a cross-polarization
The proposed antenna has a cross-polarization
level of less than 20 dB below the co-polarization for both ports.
As illustrated in Figure 5, null cross-polarization
and equal radiation patterns for the two polarizations are enforced.
The simulated pattern results showed low sidelobe level properties and low cross-polarization
features at the principle plane.
It can be seen that radiation patterns in the xz-plane are omnidirectional and have low cross-polarization
fields are created in the scattered waves to satisfy the MI boundary upon the cylinder.
The effect of cross-polarization
is lower than co-polarization which is desired.
Built-in Cross Polarization Interference Cancellation (XPIC) with Cross-Polarization
Improvement Factor (XPIF) doubles capacity without additional frequency licensing expenditure, offering an opportunity to contain capital expenditure.
