This paper present the design and simulation of a circular patch antennas integrated with low pull in voltage novel iterative meander RF MEMS switch. The transmitting signal can be alternatively switch from 40 to 60 GHz by actuating the switch beams placed on the feeding line of patch antenna. The switch—B is actuated to allow the RF (radio frequency) signal to pass through switch—A to radiates the signal at 40 GHz and it is vice versa for the signal is radiating at 60 GHz. This type of antenna is used for future 5G (5th generation) mobile communication applications. The switch utilizes 1.6 V of actuation voltage and 1.63 µs (micro seconds) of transition time to displace the beam from upstate to downstate. It exhibits very low return loss and insertion losses of − 56 dB (decibels) and − 0.19 dB at 40 GHz (gigahertz), respectively and shows high isolation of − 37.5 dB at 45 GHz such that efficiently used for millimeter wave applications. The two circular patch antennas are designed at 40 GHz and 60 GHz shows good performance characteristics and are alternatively switch between them when signal conjunction occurs. The characteristics of switch and antennas are studied by using FEM (finite element modeling) tools such as COMSOL, HFSS 13.0 V and CST 15.0 V and tunability of the antenna is achieved efficiently for 5G mobile applications.
