  Venus was observed at frequencies of 1297.67 MHz (23 cm), 607.67 MHz (49 cm)
and 233.67 MHz (1.28 m) with the Giant Metrewave Radio Telescope (GMRT) during
the period of 25th July and 6th September 2015 when it was close to its
inferior conjunction. Values of the brightness temperature (Tb) of Venus from
these observations were derived as 622{\pm}43 K, 554{\pm}38 K for 1297.67 and
607.67 MHz frequencies, respectively, are in agreement with the previous
observations. The attempt to derive the Tb at 233.67 MHz affirms an upper limit
of 321 K which is significantly lower than the previously reported upper limit
of 426 K at the same frequency. We also present the dielectric constant
({\epsilon}) values of the Venus surface estimated using the degree of
polarisation maps of Venus, derived from the GMRT polarisation observations and
theoretical calculations. The {\epsilon} of the Venus surface was estimated to
be ~4.5 at both the 607.67 MHz and 1297.67 MHz, close to the reported values of
{\epsilon} of 4 to 4.5 from the radar-based observations including the Magellan
observations at 2.38 GHz (12.6 cm).
