4G LTE TLE GSM PCB Antenna High Gain Internal Dual Band 2.4G/5G WiFi 10dbi 3dbi 1800/2600MHz for Improved Communication Signal

A single PCB antenna needs to cover multiple frequency bands simultaneously, or multiple dedicated antennas for different frequency bands can be integrated into a single system through a multiplexer to achieve the suppression of all communication links for the unmanned aerial vehicle.
