1Overview

The u-blox ANN-MB multi-band (L1, L2/E5b/B2I) active GNSS antennas are designed to reduce time
to market for the next generation of high precision GNSS applications, which require highly accurate
location information. The compact design, excellent price to performance ratio, and versatile
mounting and connector choices provide customers with fast, easy, and reliable multi-band antennasolutions. The ANN-MB antenna is a perfect match to the u-blox F9 platform, including the ZED-F9P
module, thus providing customers with a valuable antenna solution to minimize design-in efforts.
The ANN-MB series includes a high-performance multi-band RHCP dual-feed patch antenna element,a built-in high-gain LNA with SAW pre-filtering, and a 5 m antenna cable with three connector options(SMA, SMB, MCX).

6Antenna characteristics

6.1 Block diagram
A simplified block diagram for ANN-MB multi-band antenna series is shown in Figure 2. The block
diagram is divided into patch antenna element and amplifier sections. The patch antenna element
section is specified in Table 1 and the amplifier section in Table 2. The 5 m coaxial cable is connectedto the amplifier section output.

Figure 2: Simplified ANN-MB series block diagram

6.2 Antenna phase center
Typical values for the absolute antenna phase center offset in L1 and L2 bands are given in Table 7.
The phase center offset is given in millimeters with respect to the antenna reference point defined inFigure 1. The “North” direction is toward the cable connector. The “Up” direction is normal to theantenna ground plane, toward the patch element.

☞The phase center offset is measured on a circular ground plane with 120 mm diameter. Anychange in ground plane size or shape may affect the phase center offset.

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. Thecoordinate 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.
