2.3 Antenna
The ACX ceramic antenna is mounted on the EM board with a specific layout and matching circuit for the
radiation tests conducted in FCC, CE, and IC certifications. Figure 2-3 shows the location of the ACX
ceramic antenna on the EM board and the RF trace routing from the CC3000 module to the antenna.
Figure 2-4 shows the matching circuit between the antenna and the EM board. The return loss is based
on the matching circuit and RF trace routing, as shown in Figure 2-5. Figure 2-6 shows the radiation
patterns on XY, XZ, and YZ planes.
