Communication Satellite Payload Antenna
2020Based on the analysis of the characteristics of the payload antenna of communication satellite, this chapter goes deep into the functions design of some typical antennas, such as shaped reflector antenna, multi-beam antenna and adaptive nulling antenna. Finally, this chapter briefly introduces the technology of deployable large-scale mesh reflector and

Inter-Satellite Link (ISL) refers to the communication link between satellites, which can replace the ground relay station to do the autonomous operation of satellite constellation. This chapter provides two kinds of ISL antennas with beam scanning capability: the movable spot-beam reflector antenna and the phased array antenna.

Satellite-antenna measurement techniques
IEE Proceedings A Physical Science, Measurement and Instrumentation, Management and Education, Reviews, 1980Initially, the review takes a brief look at the various types of antenna systems that are used on satellites and shows that in terms of the measurement of their radiation characteristics, they can be categorised into two groups, i.e. low-gain (omnidirectional and quasi-omnidirectional) antennas, and medium- and high-gain antennas. With the first group,

Planar antennas for satellite reception
IEEE Transactions on Broadcasting, 1988Direct broadcast satellite (DBS) reception requires a circularly polarized antenna with high gain and low axial ratio. Recently, various types of planar antennas have been studied and developed for DBS reception in the 12-GHz band. A summary is presented of properties and classification of planar antennas both commercialized and reported.

Antennas for Satellite Systems
19th European Microwave Conference, 1989, 1989The paper begins with a review of satellite systems for communications and broadcast and briefly alludes to the significant scientific space programmes which act as a technology driver for the industry. Progress in satellite antennas is considered under the headings array-fed reflectors and shaped-reflectors.

Antennas for Modern Small Satellites
IEEE Antennas and Propagation Magazine, 2009Modern small satellites (MSS) are revolutionizing the space industry. They can drastically reduce the mission cost, and can make access to space more affordable. The relationship between a modern small satellite and a ldquoconventionalrdquo large satellite is similar to that between a modern compact laptop and a ldquoconventionalrdquo work-station ...
