Accurate time-domain modelling of MEMS antennas for wireless telemetry systems

A singularity-expansion-method-based technique for the accurate time-domain modelling of reconfigurable MEMS antennas for wireless telemetry applications is presented. Closed-form expressions of the radiated electromagnetic field in time domain are derived in terms of the newly introduced incomplete spherical Bessel functions depending on the complex frequencies of the natural resonant processes occurring in the antenna. © 2010 EuMA.
