Magnetars are extremely high magnetic neutron stars. Magnetars have higher X-ray luminosity than their spin down luminosity. Our of 30 know magnetars only 6 are known to emit in radio wavelengths. PSR J1818-1607 are radio magnetar with periodicity 0.733417(4) Hz and spin period derivative pdot = 9 +/- 1 * 10^(-11). Radio emission from this magnetar has very high degree(80 to 90 percent) of linear polarization. Ibrahim et. Al. (2023) report a SNR shell from VLA observation at 3 GHz. I intend to present finding of imaging observation toward magnetar PSR J1818-1607 made using upgraded Giant Metrewave Radio Telescope (uGMRT). We didn't find any evidence for the shell at 407 MHz and 643 MHz and will discuss the implications.
