The big antenna structure

Most big d-polarization antenna for ceramic medium, its components are: ceramic antenna module, cables, connectors, low noise signal. Ceramic antenna which is also called passive antennas, PATCH antennas, medium, it is the core technology of the big antenna. 　A big antenna signal receiving ability, largely depends on the ceramic part of the constituent ingredients. Module, also known as LNA low noise signal, signal amplification and filtering is part of the. 　The component selection is also important, otherwise it will increase the Beidou signal reflection loss and cause excessive noise. Cable choice is to reduce the reflection as a standard, guarantees of impedance matching.
