Antenna System

•Antenna Array
–Amplitude or Phase comparison Array (Directivity)
–Beamforming (Steering)
•Multiple Antennas
–Diversity (Range)
–Multiplexing (Throughput)
•Antenna and RF Front-end Integration
–Antennas plus Transformers (Efficiency)
–Antennas plus Filters (Out-of-band Isolation)
–Antennas plus Switches (In-band Isolation)
–Antennas plus Beamformers (Cost-effectiveness)
–Antennas plus Couplers (Concurrency)
