Thin Film Based Antennas





Defence Science and Technology Labs, Ministry of Defence, UK (Contract no. RD028-08228):
The work was on explosive detection. When a sample of explosives like RDX or TNT is excited by radio signals, it results in emission of radio signals of magnetic field in the range of picotesla to femtotesla which cannot be detected by conventional radio filters. We used MEMS and piezoelectric material based novel filters in order to detect magnetic fields. We could detect magnetic fields of the order of picotesla at room temperature.

Network Rail, UK:
The work was commissioned by Iain Coucher, the CEO of Network Rail to Dr. Sinha on structural monitoring of railway tracks managed by the Network Rail (Project No. RMVP/RPT/0304). Sensors were connected to the railway track in order to monitor the vibrations. Rock drop measurements were done at different sights and sensors could pick up object drops from a distance of a km. Monte Carlo based analysis was done in order to filter out noise. Eventually, signal related to rock drop on a railway track could be filtered out against the backdrop of huge noise generated by the motion of railway track.


Thin Film Based Antennas: The form factor of an antenna can be reduced by using certain thin films having a specific electrode patterns. The antennas work in the range of 800 MHz to 3 Ghz and have an efficiency of 60-70% with a gain close to 1.
