Description

TECHNICAL FIELD [0001] The present invention relates to a wireless communication system using a multi-band antenna for helmet surface mounting,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wireless communication system in which communication equipment is integrated into a helmet, and more particularly, to a system capable of wireless communication with the outside using a multi-band antenna for helmet surface mounting usable in a triple band.

Modern warfare is evolving into a tactic for sharing, identifying and judging battlefield information through battlefield reconnaissance resources and neutralizing the enemy with immediate precision strike.

Therefore, the command post requires a communication system that can judge the battlefield at a glance through the tactical command automation system, share battlefield information with the combatants of the frontline subcomponents, and increase the effective mission performance and viability

For the purpose of this operation, a combat unit, such as the one shown in FIG. 1, is mounted on the X-band shoulder strap of a combat bottle and is used for voice communication.

However, the current radio has a problem in that it uses a weight and a long antenna to increase the risk of breakage due to vibration and protruding shape at the time of starting, and to limit the real - time airborne communication at the time of battle. In addition, even when using the headset handset or ear microphone during operation, the length of the connection line is exposed from the shoulder to the ear for a long time, and the movement radius of the connection line is limited when the head is turned away from the outside.

Currently, the transceiver only transmits and receives voice data at 158MHz. However, in future battlefields, it is necessary to transmit the image of the battlefield and the survival status of the combatant so as to increase the combat operation and the efficiency of the combat operations through quick judgment at the command post. In addition, there is a demand for the development and use of the "Unified Communication Network Operation Helmet" by the Ministry of Land, Infrastructure and Transport, which can share the national disaster safety communication network and cooperate with firefighting, police, and local autonomous entities, .

In other words, NCW (Network Centric Warfare) 's complete front - line operation concept should be completed by monitoring real - time voice and image information exchange and survival with each combatant during operations,
