Reconfigurable Magneto-Electric Dipole Antennas for Base Stations in Modern Wireless Communication Systems

Table 1

Comparison between ME dipole with other reconfigurable directional antenna candidates.

Reconfigurable directional antenna candidates	Bandwidth	Unidirectional radiation patterns (front-to-back ratio, cross-pol)	Difficulty level to be integrated with tuning mechanisms
Patch antenna  [1]	Narrow	Poor	Easy
Cavity-backed slot antenna   [12]	Fair	Fair	Easy
Yagi-Uda antenna; [13]	Fair	Fair	Difficult
Dipole; [2]	Wide	Good	Difficult
ME dipole	Wide	Excellent	Fair
