Tantrayut Telecommunications Private Limited
This is a startup company in Mumbai region and got incorporated in Sept 2014. This startup aims at providing consultancy services in the core areas of Telecommunication Hardware. It focuses on design services and prototype product development in the areas of antennas, RF & Microwave. It aims for indigenous design and affordable manufacturing of the Telecom hardware to suit it's customer needs. 


Constantly Innovate to push the Technology to the limits set by Physics!

Tantrayut 
The word 'Tantrayut' is derived from ancient language 'Sanskrit' and it is an addition of two different words 'Tantra' and 'Ayut'. The first word symbolizes technology while the later one signifies unbounded or limitless nature. The choice of these words together could be interpreted as 'Technology Without Bounds!'. In reality the bounds are always set by physics. The art of engineering is then to push the technology as close as to the limits set by fundamental physics.

Founded by Dr. Yogesh Karandikar
Dr. Yogesh received his PhD degree from Microwave Electronics Laboratory, Dept of Microtechnology and Nanoscience at Chalmers Univerisity of Technology, Gothenburg, Sweden in 2012. He has considerable experience in the areas of Antenna Design, RF/Microwave Passive as well as Active Components Design. Through Tantrayut Telecommunication Dr. Yogesh practices his consultancy services as well as prototype product development.
