Low Connectivity range on ESP32C6

[@ADEngineer]

The network joining range of esp32c6 with pcb trace antenna is 50cm max. my requirement is upto 5m. The problem is the coordinator requires to be within 50cm for any router or end device to be rejoined to the network. I need help regarding the issue and I am also receiving the warnings like this...
W (369) phy_init: failed to load RF calibration data (0x1102), falling back to full calibration
W (429) phy_init: saving new calibration data because of checksum failure, mode(2)

The PCB trace antenna on the ESP32-C6 is often limited in range due to its design, which may not provide optimal radiation patterns compared to external antennas. A 50 cm range is pretty low for Wi-Fi or Zigbee, especially in environments where more distance is required.
