Magnetoelectric Dipole Antenna Arrays [PDF]
IEEE Transactions on Antennas and Propagation, 2014 A planar magnetoelectric (ME) dipole antenna array is proposed and demonstrated by both full-wave analysis and experiments. The proposed structure leverages the operation of composite right/left-handed transmission lines under balanced conditions to form high-gain magnetic radiators, combined with radial conventional electric radiators, where the ...
