It is recommended to use linear polarization. 4) Radiation pattern Radiation pattern refers to the antenna’s electromagnetic field strength in the far field in all directions. Half-wave dipole antenna is the most suitable terminal antenna. For built-in antenna, PIFA antennas or IFA antennas are recommended: Antenna area: 6mm high*10mm wide*100mm long. Antenna radiation direction: Omni_directional(all direction).
NL668-LA-01 module main antenna requirements Input power Standing wave ratio recommended > 23dBm average power WCDMA & LTE ≤ 2:1 Table 7-6 Main Antenna Requirements 7.5.2 Antenna reference design Antenna is a sensitive device, susceptible to the external environment. For example, the size of the module, the location of the antenna, the space it occupies, and the surrounding ground all may affect antenna performance.
Figure 7-2 GNSS Antenna Reference Circuit Note： ⚫ All matches must be placed close to antenna to make sure the characteristic impedance of transmission cable is 50 ohms. ⚫ Since the antenna loss should be less than 0.3dB, keep PCB cable as short as possible. ⚫ Keep the PCB LAYOUT straight, and reduce holes on the route to another layer; also avoid right-angle and acute-angle wiring. ⚫ PCB cable should have a good reference ground to avoid other signal cable near the antenna.
