Scientific Collaborations
 
International Collaborations:

  • 2013- present: Collaborative research work on Millimetr and THz antennas, Prof. Mohamed Himdi , IETR,  University of Rennes1, France.

 

  •    Involvement in Research Project

 

  • University: King Saud University, Riyadh, KSA
  • 2016-2018 : Luneburg Lens  and Substrate Integrated Waveguide Based Beam Steerable   Antenna Array for 60-GHz High-Speed Indoor Communication Systems, funded by National Plan for Science and Technology, KSA. Value of grant :1.98M SR (528K US$) Investigators : Hamsakutty Vettikalladi (PI) and Majeed Alkanhal (CO-I)

Summary : Wireless technology has become an accepted and critical part of our everyday lives. The demand for newer technologies to deliver wide bandwidths is higher than ever before. The end users of these technologies range from corporate data centers to teenagers with iPhones demanding more bandwidth. A relatively recent and fundamental event is the appearance and rapid growth of the personal area network (PAN), Wi-Fi, high-definition video, automotive radar and high-resolution imaging markets, which have created a sudden need for extremely broadband gigabytes-per-second (Gbps) communication systems. A natural candidate for high-speed data transfers is the 60-GHz frequency band, which has been declared unlicensed worldwide. It can offer up to multi-Gbps wireless connectivity between short-distance electronic devices. Compared to today’s wireless local area network (WLAN) technologies, the data rate is predicted to be 50-100 times faster than today’s WLAN technologies. 

  • 2014-2016: 79 GHz Short Range Radar Antenna Design for Next Generation Intelligent   Automotive Radar System, funded by King Abdul Aziz City for Science & Technology, KSA. Value of the grant : 1.74M SR (464K US$). Investigators : Hamsakutty Vettikalladi (PI) and Majeed Alkanhal (CO-I)

Summary: Automotive radars are an essential part of future intelligent vehicle safety system to reduce maximum road accidents. The latest reports saying that, every year 1.2 million people are known to die in road accidents worldwide and as many as 50 million are injured. Even in Europe itself each year nearly 1.2million traffic accidents with more than 40,000 fatalities, costs about more than 200 billion euro economic damage. In road accidents Saudi Arabia stands a reasonable position in Middle East. Highly efficient CAR Radars which will cover the surroundings of the vehicle are needed to reduce the accident to minimum. The application of automotive radar includes a) Adaptive Cruise Control (ACC) b) Collision warning /mitigation/avoidance c) Stop and go functionality d) Lane change warning/aid e) Blind spot detection f) Parking aid/back drive assistance. Nowadays car radar working at 24 GHz for Short Range radar (SRR) and 77GHz for LRR (for front and rear) is available but which does not cover the entire surroundings of the vehicle. Latest report from National Highway Traffic Safety Administration (NHTSA) saying more than 15% of the accidents are from sides. Also in Europe the sunset date of 24 GHz SRR is June 2013 but now it extended till 2018. In reality a minimum sunset date of 2022 is needed to bridge the technology gap – keeping in mind that some manufacturers could start with 79 GHz technology as early as 2018.  79 GHz SRR is not available in the market at present which may take five more years to develop. Antenna is one of the fundamental units in all RADAR systems. One of the main hurdles in designing antennas is to find out the best technology at this frequency. The technology used in 24 GHz is not suitable for 79GHz. Hence innovative antenna technology is to be developed.
