CRS’s tri-band GPS antenna is the world first tri-band GPS antenna to cover three GPS bands (L1, L2 and L5). It is compact in size and has excellent multipath rejection capabilities. This antenna eliminates both co- and cross-polarization signals coming below the horizon. Superior cross-polarization rejection (-20dB) is achieved in upper hemisphere. The antenna is equipped with a new type of vertical choke ring developed by CRS (U.S. Patent 6,940,457 Sept. 6, 2005). The ring has identical performances to conventional choke rings, but at a greatly reduced size (25 percent smaller). Unlike conventional choke rings, it is designed to be effective for all operating frequencies. Typically, the multipath signal is in both polarizations. For a good multipath resiliency, the antenna must have minimal reception from the back size of the antenna for both polarizations. CRS's tri-band antenna takes the best countermeasure for this requirement.
