Production Information

6.3 Radiation pattern

The radiation pattern in the L1 and L2 bands are shown in Figure 4 and Figure 5, respectively. The 2-D

cuts for

H (xy), E1 (xz), and E2 (yz) planes are shown at BeiDou, GPS, and Glonass frequencies. The

coordinate axes are defined in Figure 3.

☞ Note: The spherical coordinate system used represent radiation pattern data is different from the

“North”, “East”, “Up” coordinate system used for antenna phase center offset in section 6.2.

Figure 3: Definition of coordinate axes for radiation pattern plots.

Figure 4: Radiation pattern in L1 band. The 2-D cuts are measured at 1559 - 1606 MHz (nine frequencies).

Figure 5: Radiation pattern in L2 band. The 2-D cuts are measured at 1197 - 1249 MHz (nine frequencies).
