Dual-band conformal meander-line monopole antenna with coupled patch for unmanned aerial vehicle applications

In this paper, we present a meander-line monopole antenna for Unmanned Aerial Vehicle (UVA). In order to improve the resonant characteristic and expand the bandwidth, a couple of coupled patches have been added. It also improves the radiation characteristics in higher frequency. The antenna realizes omni-directional radiation in the horizontal plane when operating in780MHz-900MHz and 1.20GHz-2.28GHz. The antenna is conformed on the side of airframe and can be widely used as communication antenna on UVAs for its performance of dual-band and wideband.
