Beam-switchable Magneto-Electric antenna array based on composite right/left-handed (CRLH) structures

The beam-switching characteristics of Magneto-Electric (ME) dipole antenna array is presented based on differentially exciting the two ports of the array with different polarities. The proposed principle is demonstrated using full-wave simulations that the depending on the polarity of the two excitations, either a magnetic-dipole or an electric-dipole radiation can be selectively achieved.
