Wideband and UWB Antennas for Wireless Applications: A Comprehensive Review

Figure 21

A monopole antenna making use of a zig-zag shaping of the upper edge of the ground plane [76]. The adopted zig-zag profile allows performing a more effective electromagnetic coupling between the feeding line and the monopole in a more extended frequency band.
