Theoretical investigation of possible application of microwave planar antennas for the development of telecommunication devices based on magnetic nano-structures (MNS) (spin-torque nano-oscillators) is presented. It is shown that coplanar antennas have some advantages in comparison with other types of antennas. The performance of the antennas in a frequency range 1-5 GHz is estimated, and it is shown that considered antennas have sufficiently good parameters and can be used for the development of telecommunication devices based on MNS.
