Provided is a dual-polarized antenna. The dual-polarized antenna includes a horizontal radiating unit and a vertical radiating unit. The horizontal radiating unit includes a power divider and a Vivaldi oscillator array. The Vivaldi oscillator array includes multiple Vivaldi oscillator units uniformly distributed in a circumferential direction of the Vivaldi oscillator array. The power divider includes multiple output ports in one-to-one correspondence with the multiple Vivaldi oscillator units. The multiple output ports of the power divider are coupled to the multiple Vivaldi oscillator units in a one-to-one correspondence. The vertical radiating unit is disposed on one side of the horizontal radiating unit and includes a vertically-polarized oscillator.

A microstrip line filtering radiation oscillator, a filtering radiation unit, and an antenna, the oscillator includes a substrate. A plurality of first metal sheets parallel to each other are arranged at intervals on a front surface of the substrate, a plurality of second metal sheets parallel to each other are arranged at intervals on a back surface of the substrate, and the first and second metal sheets are correspondingly staggered and coupled by a coupling part running through the substrate. The microstrip line filtering radiation oscillator has functions of signal radiation and interference suppression. The filtering radiation unit includes at least one oscillator and can be used in conjunction with a high-frequency radiation unit, to radiate high-frequency and low-frequency signals simultaneously. The antenna includes at least one filtering radiation unit, and can transmit low-frequency and high-frequency signals simultaneously, thereby effectively improving the integration and reducing the volume of the antenna.

A transparent broadband antenna has two conductive leaves that are configured to be axially symmetric about two orthogonal axes. The transparent broadband antenna is designed as having two back-to-back Vivaldi radiators and four identically curved outer corners. The back-to-back Vivaldi radiators provide high performance from 617 MHz through 7 GHz while preventing return waves that may cause impedance mismatch. The antenna further comprises a feed structure that enables direct coupling from an RF cable to the two conductive leads, obviating the need for a matching circuit and subsequent bandwidth limitations.

An antenna element includes a dielectric substrate, a radiation electrode, a first ground electrode, a second ground electrode, and a via conductor that connects the first ground electrode and the second ground electrode to each other. The dielectric substrate includes a flat-plate-shaped first part and a second part that is thinner than the first part. The radiation electrode and the first ground electrode are arranged on or in the first part so as to face each other in the thickness direction of the first part. The second ground electrode is spaced apart from the radiation electrode. The second ground electrode is arranged on or in the second part so as to not face the radiation electrode in the thickness direction of the second part. The radiation electrode is capacitively coupled to the second ground electrode and the via conductor.
