Frequency and Beam Reconfigurable Antennas for MMMB Communication Systems
In this paper, four reconfigurable antennas are presented for multi-mode multi-band (MMMB) communication systems. Each antenna is able to reconfigure diverse operational frequency bands or beam directions depending on the states of embedded switches, which are implemented using pin diodes or RF-microelectro-mechanical system (RF-MEMS) switches.

متن کاملMicroelectrical Mechanical Systems Switch for Designing Multi-Band Antenna
Problem statement: In this study Microelectrical Mechanical System (MEMS) switches were proposed to design a reconfigurable/multi-band antenna to replaced PIN diode switches or semiconductor switches due to lower insertion losses, good isolation, much lower intermodulation distortion, and lower power consumption. The antenna is able to operate at very high frequencies. Approach: A reconfigurabl...
