A dual-frequency, dual-polarized magnetoelectric
dipole filter antenna is disclosed, relating to a magnetoelectric
dipole antenna. It includes a bottom
dielectric substrate, a feeding structure, a
magnetic dipole dielectric substrate group, an electric
dipole dielectric substrate, and a filter
magnetic dipole dielectric substrate group. Slots are provided on the bottom
dielectric substrate for connecting and fixing the filter
magnetic dipole dielectric substrate group; slots are provided on the electric dipole dielectric substrate for the filter magnetic dipole dielectric substrate group to pass through. The magnetoelectric
dipole antenna structure generates a low-frequency
radiation null point I, extends the end
microstrip line of the
microstrip power divider to obtain an intermediate-
frequency band radiation null point II, introduces an intermediate-
frequency band filter magnetic dipole patch to obtain an intermediate-
frequency band radiation null point III, and a slot structure is provided in the connection structure between the magnetic dipole and the electric dipole to obtain a high-frequency
sideband radiation null point IV. A high-frequency out-of-band filter magnetic dipole patch is introduced to obtain a high-frequency radiation null point V. The filter magnetic dipole is located inside the magnetoelectric
dipole antenna, without increasing the antenna profile height and outline dimensions, eliminating the need for a filter network, and achieving dual polarization and dual-frequency
bandpass filtering.
