     Antenna Systems for Next Generation navigational and High Frequency Satellites

    A brief introduction to satellite communication antennas will be given at the beginning of this talk. Next generation satellite systems for navigational and high frequency payloads require advanced antenna systems to meet the demanding requirements in terms of generating plurality of beams from a single antenna array, beam reconfigurability, multiple bands, low-loss antennas, and stable phase center with frequency for better location accuracy. The talk will focus on existing technologies, limitations, advantages of the next generation payloads, RF performance and hardware implementation. An L-band array working at three frequency bands and generating a number of beams simultaneously is discussed including design and RF performance. This will employ digital payload to generate multiple beams at multiple bands supporting commercial and military users. A dual-band antenna working at very high frequencies for future payloads capable of a ten-fold increase in satellite capacity will be discussed. Relevant antenna designs and hardware aspects will be discussed. Test results of the satellite antenna and ground terminal will be presented. This talk will be beneficial for engineers working in antenna industry, researchers, and academia.
