A better understanding of effect of antenna polarization
and the use of multiple antennas has led to better data quality in terms of how the earth is sampled to detect and image targets.
Furthermore, as there is no antenna polarization
it is possible to transmit data without any performance loss, regardless of the contact angle of the electronic devices.
For the purposes of this discussion, you can simply think of the antenna polarization
as a special marker on an antenna that indicates "this way up".

Critical topics that readers would otherwise have to search a number of resources to find are included: RF safety chapter provides a concise presentation of FCC recommendations, including application examples, and prepares readers to work with real-world propagating systems; Antenna chapter provides an introduction to a wide variety of antennas and techniques for antenna analysis, including a detailed treatment of antenna polarization
and axial ratio; the chapter contains a set of curves that permit readers to estimate polarization loss due to axial ratio mismatch between transmitting and receiving antennas without performing detailed calculations.
15 /PRNewswire-FirstCall/ -- Harris Corporation today announced that it has successfully completed multiple field demonstrations of a satellite antenna feed prototype that is capable of supporting selectable antenna polarization
for satellite orthogonal transmit and receive operations.
An advanced control center allows engineers to control turntable position, antenna polarization
and height from one to four meters, providing for rapid compilation, documentation and reporting of test data.
For best performance, the antenna polarizations
