... polarizer is introduced between the OMT and the antenna-feed in order to convert the incoming linearly-polarized signals into left- and right-hand polarizations (Virone et al., 2008). Finally, the ... operated in the L ( 1-2 GHz) and S ( 2-4 GHz) bands, whereas remote-sensing applications are mostly offered in C ( 4-8 GHz) band. In the commercial communication area, due to t...
