We present results of interferometric polarization observations of therecently discovered magnetar J1745-2900 in the vicinity of the Galactic center.The observations were made with the Karl G. Jansky Very Large Array (VLA) on 21February 2014 in the range 40-48 GHz. The full polarization mode and Aconfiguration of the array were used. The average total and linearly polarizedflux density of the pulsar amounts to 2.3$\pm$0.31 mJy/beam and 1.5$\pm$0.2mJy/beam, respectively. Analysis shows a rotation measure (RM) of(-67$\pm$3)x10$^3$ rad/m$^2$, which is in a good agreement with previousmeasurements at longer wavelengths. These high frequency observations aresensitive to RM values of up to ~2x10$^7$ rad/m$^2$. However, application ofthe Faraday RM synthesis technique did not reveal other significant RMcomponents in the pulsar emission. This supports an external nature of a singlethin Faraday-rotating screen which should be located close to the Galacticcenter. The Faraday corrected intrinsic electric vector position angle is16$\pm$9 deg East of North, and coincides with the position angle of thepulsar's transverse velocity. All measurements of the pulsar's RM value todate, including the one presented here, well agree within errors, which pointstowards a steady nature of the Faraday-rotating medium.
