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 10-2 provides a summary of the recommended antennas to use with the CC3135MOD module.

Table 10-2 Antenna Guidelines
SR NO.GUIDELINES
1Place the antenna on an edge or corner of the PCB.
2Ensure that no signals are routed across the antenna elements on all the layers of the PCB.
3Most 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.
4Ensure 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.
5Ensure that the antenna impedance is 50 Ω because the device is rated to work only with a 50-Ω system.
6In case of printed antenna, ensure that the simulation is performed with the solder mask in consideration.
7Ensure that the antenna has a near omni-directional pattern.
8The feed point of the antenna is required to be grounded. Refer to the specific antenna data sheets for the recommendations.

Table 10-3 lists the recommended antennas to use with the CC3135MOD module. Other antennas may be available for use with the CC3135MOD module. Please see the CC3135MOD OEM Integrator's Guide for the full list of supported antennas.
