COJOT Mission Adaptive Antenna Range

Alaris Antennas sister company, COJOT, has a Mission Adaptive Antenna range which provide superior performance for mission critical vehicles, manpacks and handheld radio communications.

The MIDAS (Mission Adaptive Antennas) range provides optimized performance over a wide frequency range resulting in better link budgets and radio coverage together with higher interference rejection.  As a result of their enhanced electrical performance, additional aspects like a reduction of the radio system’s power consumption, or using antennas of shorter height become possible to consider.

These Mission Adaptive antennas use active matching, which is 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 switching technology used in the mission adaptive antennas is controlled by the radio or autonomously by the antenna. The control signal and supply voltage are fed to the antenna through the connector or through a separate data connector.

There are three types of mission adaptive antennas in this range:

Vehicle

These mission adaptive antennas, covering the 30 to 90 MHz and 30 to 520 MHz frequency ranges, offer superior gain performance with fast tuning abilities.

Manpack

These compact antennas provide up to 10 dB gain improvement over antennas with passive matching.

Handheld

These antennas are for handheld SDRs working in the 30 to 520 MHz frequency band.

The benefits of the COJOT Mission Adaptive Antenna Range are:

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