Smart antennas are important for SATCOM on-the-move (SOTM) because they can increase the channel capacity and coverage range of the communication systems. Firstly, this paper briefly reviews the state-of-art on the smart antenna design for SOTM applications. Different types of antenna for SOTM are discussed. Then, two design examples from the recent collaborated research work from the University of...
This paper presents a polarization reconfigurable printed loop antenna which could alter its polarization states electronically to right-hand circular polarization (RHCP), left-hand circular polarization (LHCP) or linear polarization (LP). By inserting four PIN diodes into the symmetric gaps of a dual-loop planar antenna, the proposed antenna can switch its polarization status by controlling the on-off...
Smart antenna is important for satellite communications because it can increase the channel capacity, spectrum efficiency and coverage range of the communication systems. The smart antennas can be categorized into two types: beam-switching smart antenna and adaptive smart antenna. This paper overviews the technology for both types of smart arrays with general system architecture and design examples...
