Magnetoelectric Dipole Antennas with Dual Open-Ended Slot Excitation

Designs of novel magnetoelectric dipole antennas excited by dual open-ended slots for both single and dual linear polarizations are presented in this paper. The antenna can be interpreted as a dual complementary source that exhibits lower profile and higher gain while maintaining excellent radiation characteristics of the original ME dipole, including wideband, low back radiation, and high polarization purity. In addition, high isolation is obtained in the dual polarization design. All the above characteristics show that the proposed antennas can be regarded as potential candidates for various wireless applications. Prototypes are fabricated and measured to confirm the simulation results.
