Abstract:
In the past years, RF MEMS devices have proven to be a vital part in development of
complex essential devices which include consumer applications, wireless applications, industrial
applications, and medical applications just to name a few. 5G is the key to the future. From
communication applications to smart home solutions, 5G unlocks it all. We want to develop a
switch for extremely high frequency band particularly focusing on 5G band and its applications.
This work targets the design of an in-plane capacitive switch that is compatible with 5G for
applications in the EHF frequency band. The previous designs focus on shunt switches. Analyzing
the complete working of the switch is also a focus in this research. The dual and quad mode of the
switch presented provide ample payload distribution for satellite systems. A displacement
actuation mechanism has been employed in the switch design to enhance displacement provided
by electrothermal actuators which improves the performance of the switch. The performance of
the switch is analyzed by performing electrothermal, structural and electromagnetic analysis on
the switch such that all the parameters are optimized for close to ideal RF characteristics. The
results are benchmarked against published data and show improvements made in the design
