Design considerations and challenges of integrating on-chip antennas in nanoscale CMOS technology at millimeter-wave (mm-wave) to achieve a compact front-end receiver for 5G communication systems. Solutions to overcome these challenges are offered and realized in digital 28-nm CMOS. A monolithic on-chip antenna is designed and optimized in the presence of rigorous metal density rules and other...

G/Tsys defines the sensitivity of a radio telescope and is an important figure of merit. It is important to know the overall antenna efficiency and system noise temperature of the telescope in order to calculate the G/Tsys. In order to calculate the G/Tsys for uGMRT bands, a Software was developed in-house at GMRT-NCRA, named as RASCAL (Reflective Antenna Sensitivity CALculator).

RFoF technology enables a path for low loss signal transmission over longer distances, carry huge bandwidth of data, and is also immune to electrical noise. The paper discusses the technology, design, and methods for implementing it for phased array antennas application. The RFoF backplane is very much compact and suitable for phased array antennas, these replace the need for bulky RF cables,...

We describe here the electronics aspects of the 3.6 m Devasthal Optical Telescope (DOT) and discuss the strategic approach adopted by the ARIES electronics engineering team for maintaining and upgrading the telescope. The construction of the 3.6 m DOT was completed at the AMOS Factory in Belgium in the year 2012 and the telescope was partially disassembled into its sub-systems and transported...
