Beam-Steering technologies in antenna system is used to achieve high gain and wide area coverage. As the consumer market is adopting more mmWave frequency for 5G, satellite and radar applications, beam-steering technologies is becoming more and more important. Different from military application, it prefers high performance, low cost, low power and small side effects to end user. emSensing helps customers to develop phased array and RF front-end module for 5G handsets, small cell and other applications.
