Multiple-Input Multiple-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) have been widely accepted as key techniques of the current and future wireless communication systems. In this paper, an open access MIMO testbed is presented, on which the researchers can demonstrate and evaluate their baseband algorithms over the real wireless channel, without knowing much details about the...
RF MEMS devices are competitive for handling high frequency microwave signals. In comparison to semiconductor devices, the performance of RF MEMS devices is highly linear, minimizing signal distortion. A contactless piezoelectric RF MEMS switch has been designed and simulated. Due to the use of a contactless design based on variable capacitance the reliability issues affecting contacting-type MEMS...
Wireless power delivery to implantable biomedical devices by means of inductive coupling has been proved to be feasible. MEMS coils which are fabricated with micro-fabrication technology are used as the coupling coils. MEMS coils were formed by Cu electroplating with the thickness of 15μm. This paper present a new stack packaged MEMS coils which are helpful in improving the coupling efficiency. An...
This paper presents a lateral resistive-contact electrothermally actuated MEMS switch for wireless communication applications. It is manufactured on a standard low-resistivity substrate, and its RF performance was improved by suspending the structures 25μm from the substrate, which is good for future integration with active devices in the system-on-chip concept. The switch is driven by a metal electrothermal...
