RISAT-2B satellite launched on May 22 will use microwave radiation for crop monitoring, forestry and flood mapping. The satellite can image during day and night and under almost all weather conditions including cloud cover. It can detect objects with dimensions of as little as a metre, making it ideal for military surveillance. With the successful … Continue reading Surveillance from the sky using RISAT-2B satellite

NIIST researchers fabricate a wearable WiMAX antenna
The wearable WiMAX antenna is flexible, light weight and operates at around 3.37 GHertz. Since copper ink used for screen printing can get oxidised, the researchers used silver ink for printing the bottom electrode on the polyester fabric as well as the E-shaped patch antenna. Wearable antenna embedded in a multilayered polyester fabric suitable for WiMAX … Continue reading NIIST researchers fabricate a wearable WiMAX antenna
