Abstract
A wideband millimeter-wave magneto-electric (ME) dipole antenna with end-fire radiation, which is fed by the substrate integrated coaxial line (SICL), is designed, fabricated, and measured. First, the ME-dipole antenna excited by a planar L-probe is presented to realize wideband performance. Then, a wideband impedance conversion structure is used to connect the antenna and the feeding port. A simple conversion structure for the SICL to the grounded coplanar waveguide is used for the antenna test. Finally, the simulation and measurement results validate the proposed end-fire ME-dipole antenna. The overall bandwidth is greater than 40% considering both impedance bandwidth and 3-dB gain bandwidth.
