摘要：
In this communication, we introduce a high-gain, dual-polarized magnetoelectric dipole (ME-dipole) antenna utilizing patch loading. The ME-dipole consists of four short-circuited patches and four L-shaped copper blocks. It is fed by two coaxial lines and crossed microstrip lines to provide +/- 45 degrees polarization for electromagnetic wave radiation. By incorporating four parasitic patches, the impedance bandwidth and gain of the ME-dipole are enhanced, resulting in a 41.8% impedance bandwidth and a maximum unit gain of 13.7 dBi for both polarizations. The antenna is fabricated and measured, and the measurement results are consistent with the simulation results. It exhibits stable high gain and wide impedance bandwidth.
