摘要：In this paper, we propose the study, design and simulation of a pointing controller circuit (selector of beam position) for beam-switching antenna systems. This circuit is an active switch-based PIN diode (one input / eight output), designed with microstrip technology and capable of controlling eight beam pointing positions. The frequency band considered is the UMTS band, the design is performed with the substrate Fr4 (Er = 4.5 tg#948; = 0.02 h = 1.6 mm) and simulations are realized with the ADS software.
