A comprehensive review paper concerning the geometry, topology, implementation methodology, feeding mechanisms and application domain of wideband and ultrawideband (UWB) antennas for high power applications is presented. Single element antennas, reflector based antennas and array type antennas developed across the globe are taken into account. The antennas considered here are grouped based on their similarity in structure and their performance is compared based on their mode of implementation. This information provides a guidance to the selection of different geometries for various applications especially in the applications pertaining to intentional electromagnetic interference(IEMI). Few antenna models were simulated in CST for the transient response to show their typical transient responses. An exhaustive comparative table is presented with the worldwide designs and some indigenous developments.
