External Antenna Placement and Routing

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 10-4 provides a summary of the antenna guidelines to follow with the CC2651R3SIPA module when using the module with an external antenna.

Table 10-4 External Antenna Guidelines
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 impedance is 50 Ω because the module 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.

Table 10-5 lists the recommended external antennas to use with the CC2651R3SIPA module. Other external antennas may be available for use with the CC2651R3SIPA module.
