Spring constant measurement of RF MEMS switch fixed-fixed beam. The capacitive RF MEMS switch is used in a Ka-band RF MEMS frequency reconfigurable slot antenna.
If the Spring constant of the dektak stylus is not smaller than that of your device, the measurement will not tell you alot about the real stiffnes value of your device.
I agree. Fortunately for the measurement, fixed-fixed beam RF MEMS components are blessed with residual stress, making the beams stiff.
