SWRS262B February 2021 – September 2022 CC2652RSIP
PRODUCTION DATA
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. Table 10-2 provides a summary of the antenna guidelines to follow with the CC2652RSIP module.
SR NO. | GUIDELINES |
---|---|
1 | Place the antenna on an edge of the PCB. |
2 | Ensure that no signals are routed across the antenna elements on any PCB layer. |
3 | Most antennas, including the PCB antenna used on the LaunchPad™, 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 characteristic impedance is 50-Ω as the module is designed for a 50-Ω system. |
6 | In case of printed antenna, ensure that the simulation is performed considering the soldermask thickness. |
7 | For good RF performance ensrue that the Voltge Standing Wave Ration (VSWR) is less than 2 across the frequency band of interest. |
9 | The feed point of the antenna is required to be grounded. This is only for the antenna type used on the CC2652PSIP LaunchPad™. See the specific antenna data sheets for the recommendations. |
Table 10-3 lists the recommended antennas to use with the CC2652RSIP module. Other antennas may be available for use with the CC2652RSIP module. Please refer to to the CC2652RSIP OEM integrators guide for a list of approved antennas (and antenna types) that can be used with the CC2652RSIP module.
