Small printed ultra-wideband (UWB) antennas that combine electric-type and magnetic-type radiators are presented. Combining the two types of radiators can extend the passband in the lower frequency direction compared with antennas of either individual type. Moreover, combined antennas can be designed...
In this paper, a printed small Ultra-Wideband (UWB) antenna with directive radiation characteristics based on combination of electric-magnetic radiators is presented. The combinations of the electric and magnetic type antennas result in the directive radiation patterns for all observed UWB frequency ...
