We present archival Giant Metrewave Radio Telescope (GMRT) observations oftwo exoplanetary systems, $\tau$ Bo\"otis, and 55 Cancri, at 610 MHz and 150MHz, respectively. Theoretical models predict these systems to have some of thehighest expected flux densities at radio wavelengths. Both $\tau$ Bo\"otis and55 Cancri have been previously observed at low frequency ($\sim$ 30 MHz) withLow-Frequency Array (LOFAR) (Turner et al. 2020). $\tau$ Bo\"otis showstentative signatures of circularly polarized emission at 30 MHz, while noemission was detected from 55 Cancri. We do not detect radio emission from boththe systems, but the GMRT observations set $3\sigma$ upper limits of 0.6 mJy at610 MHz for $\tau$ Bo\"otis and 4.6 mJy at 150 MHz for 55 Cancri. Thesensitivity achieved at 610 MHz in these observations is comparable to some ofthe deepest images of an exoplanet field.
