Increasing Wideband Antenna Performance
with Active Matching


Better link budget through active matching

COJOT Adaptive Antennas are matched based on controlled band switching, where the frequency band is split into smaller slots and each slot is matched separately.

The RF signal is connected through the most optimal matching circuit using RF switches and fast control logic. This switching technology is compatible with frequency hopping.

The active matching is controlled by the radio or autonomously by the antenna. The control signal and supply voltage are fed to the antenna through the antenna connector or through a separate data connector.  


Advantages over passively matched antennas 

  • Better link budget 
  • Improved radio coverage
  • Extended communication range 
  • Higher interference rejection
  • Lower power consumption
  • Smaller visual signature


COJOT actively matched antennas are available for mission critical vehicle, manpack and handheld applications.
