The antenna is the element used to convert the guided waves on the PCB traces to the free space electromagnetic radiation. The placement and layout of the antenna are the keys to increased range and data rates.
The points listed in Table 10-2 must be observed for the antenna.
SR NO. | GUIDELINES |
---|---|
1 | Place the antenna on an edge or corner of the PCB. |
2 | Ensure that no signals are routed across the antenna elements on all the layers of the PCB. |
3 | Most antennas, including the chip antenna used on the booster pack, require ground clearance on all the layers of the PCB. Ensure that the ground is cleared on inner layers as well. |
4 | Ensure that there is provision to place matching components for the antenna. These must be tuned for best return loss when the complete board is assembled. Any plastics or casing must also be mounted while tuning the antenna because this can impact the impedance. |
5 | Ensure that the antenna impedance is 50 Ω because the device is rated to work only with a 50-Ω system. |
6 | In case of printed antenna, ensure that the simulation is performed with the solder mask in consideration. |
7 | Ensure that the antenna has a near omnidirectional pattern. |
8 | The feed point of the antenna is required to be grounded. This is only for the antenna type used on the CC3200MOD Launchpad. See the specific antenna data sheets for the recommendations. |
9 | To use the FCC certification of the module, refer to CC31xx & CC32xx Radio Certifications wiki page on CC3200 Radio certification |
