摘要: This chapter reviews the design and operation of user antennas for satellite communications ‐ fixed, mobile, broadcast services. review includes simple dipole antennas, progresses to Yagi-Uda then on high-gain parabolic reflector that are most commonly used in systems. The trade-off between antenna gain beamwidth is explored detail. key differences process
