Figure 6-8. Antenna 3-D Radiation Patterns
TI recommends applying the following guidelines for a proper design:
• Do not place traces or ground under and around the antenna section.
• Provide a clearance area of approximate 5.8 x 4.8 mm under the antenna area in all the PCB layers
(see Figure 6-9).
• Place the module with the antenna area fitting on the edge of the PCB (see Figure 6-9).
• Follow the ground guidelines described in Section 6.2.1.4, Power Supply and Ground Guidelines.
• In addition, consider the proximity of the antenna to the enclosure and consider the enclosure material.
