KHALID ALRUSHUD. POST-GRADUATE RESEARCH ASSISTANT, UNIVERSITY OF EDINBURGH
Khalid Alrushud was born in Al Kharj, Saudi Arabia. He received the B.S. degree in Electrical Engineering from King Saud University, Riyadh, Saudi Arabia, in 2015. In 2016, He joined the National Satellite Technology center, King Abdulaziz City for Science and Technology (KACST), Riyadh, Saudi Arabia, where he was a Communications Engineer for Saudi SAT 5A and 5B Satellites. In 2018, KACST gave him a scholarship for his higher education. He received the M.Sc. degree in Mobile and Satellite Communications from University of Surrey, Guildford, U.K., in 2019.
He is currently pursuing the Ph.D. degree in engineering with the School of Engineering, The University of Edinburgh, Edinburgh, U.K. His primary research interests include the analysis and design of small satellite antennas such as reflectors, slotted waveguide, microstrip, substrate integrated waveguides, parallel-plate waveguides and leaky-wave antennas.
Presentation Synopsis:
‘Planer end-fire antenna design using substrate integrated waveguide technology for picosatellite and other small satellites’
The work aims to design an array of end-fire antennas to support a downlink antenna system for small satellites, basically to steer the beam toward the ground station. This developed end-fire antenna design concept uses a parallel-plate waveguide launcher based on substrate integrated waveguide (SIW) technology that achieves power transfer to a grounded dielectric slab (GDS) mode as a Transfer Magnetic (TM) surface wave. Additionally, these waves transfer to the GDS by a partially reflective surface for improved matching on a chosen part of the SIW lines which is based on the leaky-wave theory. This presentation will firstly presently the theoretical approach, the full-wave simulations, and results of this antenna on a satellite for operation at 18 GHz.
