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...

A singularity-expansion-method-based methodology is proposed for the accurate time- and frequency-domain analysis and modeling of wave radiation processes in ultrawideband antennas. By means of this approach, the transient electromagnetic field distribution in the Fraunhofer region is presented in analytical closed form as the superposition of outgoing propagating non-uniform spherical waves. The...
