Published 2012 by John Wiley & Sons, Ltd. 1 GPS III antenna farm (Lockheed Martin). the centre of the array structure. 3 . The high-band element is a circular ring patch with two notches to achieve circular polarisation from a single coaxial feed point. The low-band element is excited by a pair of coaxial probes fed in quadrature to achieve the circular polarisation. An additional patch between the two elements acts as a ground plane for the high-band antenna.
E5, E6 and L1 for Galileo) seeing a nonlinear input–output characteristic and so generating a mixing effect . ). occur even at a junction between different metals that form the transmission line or antenna input terminals. Possible sources of PIM include: • Non-homogeneous contacts between metals of different types. • Presence of oxides, particularly across gaps and joints (often associated with RF connectors). • Local lack of uniformity in the conductivities of the materials involved. • Intrinsically nonlinear materials (ferromagnetic, ferrites, stainless steel, dielectrics loaded with conductive powders or granules).
