Abstract

<p>　Vital data communication is useful in preventing heatstroke during firefighting activities by firefighters. Since the communication environment may deteriorate at the fire site, it is desirable to use a wireless repeater if required. The antenna mounted on the wireless repeater is required to be able to transmit and receive regardless of the situation on the back conditions. In this paper, we proposed an artificial magnetic conductor (AMC) integrated antenna with a planar structure that can reduce the influence of the backside by using AMC and examined its characteristics by electromagnetic field analysis. As a result, the antenna combined with AMC was able to increase the gain and front-to-back ratio without significantly reducing the reflection coefficient to the antenna alone. In addition, deterioration of reflection coefficient and movement of resonance frequency could be reduced even on a metal plane.</p>
