MEMS Caps that Push Both Ways
The many bands that cellphones must support, coupled with environmental changes that can have a dramatic effect on the effectiveness of a phone’s antenna, have made the concept of antenna “tuning” particularly relevant. We looked at WiSpry’s approach to this some time ago. The concept involves an array of capacitors that can be reconfigured in real time to change the characteristics of the antenna and improve reception.
Most such MEMS capacitor arrays consist of cantilevers – like … Read More → "MEMS Caps that Push Both Ways"
