Abstract

Antenna theory is fundamental, the concepts are visionary and the applications are real. This is essentially what antenna engineering is all about. This workshop covers all aspects of satellite communication antennas including introduction to satellite communications, role of antennas in satellite payloads, antenna fundamentals, design aspects for various satellite services, analysis, advanced antenna hardware developed for various satellites, test methods and space qualification. The course will be given by 7 eminent speakers, all with satellite industry background, from USA, Europe and India having combined experience of more than 120 years!

21st century has seen several new satellite services such as local-channel broadcast for direct broadcast satellite service (DBS), fixed satellite services (FSS), high capacity K/Ka-band personal communication satellite (PCS) service, hosted payloads, mobile satellite services (MSS) employing a wide variety of antennas. These include horn antennas, TT&C antennas, phased arrays, reflector antennas, large deployable mesh reflectors, imaging reflector antennas, high power hybrid satellites etc. Antenna sub-system design, mechanical packaging on the spacecraft, and RF performance become very critical for these satellites. System requirements that drive the antenna designs will be presented initially with brief introduction to satellite communications. Antenna designs using phased arrays and reflectors will be addressed. Relevant antenna software for design and performance evaluation of these antennas using TICRA’s POS and GRASP commercial software packages will be discussed.

Practical designs for contoured beams, multiple beams, and reconfigurable beams will be highlighted during the workshop. Multiple beam antenna (MBA) concepts and their advantages compared to conventional contoured beams will be introduced. Recent advances in feed technology and reflector technology will be addressed with few examples. Topics such as antenna designs for high capacity satellites, large deployable mesh reflector designs, low PIM designs, and power handling issues will be included. Antenna test ranges and test methods will be presented in detail including far-field ranges, near-field ranges, anechoic chambers, compact ranges etc. Recent advances in test ranges with emphasis on complete payload testing and shorter test schedules will be discussed.

Qualification of antennas for space environment and associated tests such as high power, passive-intermodulation, thermal, vibration, ESD etc will be explained including typical test plan. Future trends in the satellite and ground antennas will be discussed. At the end of this talk, attendees will be exposed to typical requirements, designs, hardware, software, and test methods for various type of antennas.
