Zigbee and 802.15.4 devices use PCB trace antennas (meander line or inverted-F) etched directly onto the module PCB, connecting to the RF IC via a 50-ohm microstrip line with a clearance zone required around the antenna.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | RF Feed | 50 ohm trace feed to antenna | BUS |
| 2 | GND | Ground plane return | GND |
