Analysis of existing technical decisions on construction short-wave antennas of air-crafts which showed their unfitness for effective transmission of wireless signals from an unmanned aerial vehicle board (UAV) fulfilled of composite materials because of necessity of usage of the case as a radiating element is carried out. The conformal magnetic resonance frame antenna intended for setting in flying machine casing is developed. The radiating loop of the antenna is fulfilled on a circuit of a profile of a surface of the unmanned aerial vehicle at the expense of what there is a magnification of the area of the antenna enveloped by a circuit that in turn leads to magnification of effective operating length of the antenna in the receive mode and to increase gain amount of the antenna in the transmission mode. On the basis of the method of the moments calculation of currents in the antenna is fulfilled and the main characteristics of the antenna are defined. The comparative analysis of the developed planimetric antenna and two antennas with a radiating loop in the form of a ring is carried out. It is shown that the circular antenna does not satisfy to the condition of conformality and is unsuitable for usage on UAV with average and small sizes. At reduction of overall dimensions of the circular antenna for the purpose of possibility of its setting under a flying machine covering the gain amount essentially worsens and the antenna bandpass range is narrowed down. It is shown that the main characteristics of the offered planimetric and known circular antenna under condition of the equal area enveloped by a radiating loop differ slightly.
