[0002] The radiator in the existing dual-frequency dual-polarized antenna is composed of two or more high-frequency oscillators and low-frequency oscillators to form a high-frequency oscillator array and a low-frequency array, and the high-frequency oscillator array and the low-frequency oscillator array are respectively insulated and arranged on the reflector. On the same side of the board, there are many components, and the structure of the antenna is more complicated; moreover, the high-frequency oscillator array and the low-frequency oscillator array are arranged in the direction perpendicular to the reflector, resulting in a larger and bulkier antenna

The invention discloses a dual-frequency dual-polarized antenna. The dual-frequency dual-polarized antenna comprises a dielectric substrate, a first radiator and a second radiator; the first radiatoris arranged on the first surface of the dielectric substrate and provided with a first high-frequency band branch knot, a first low-frequency band branch knot and a first feed network; the first high-frequency band branch knot and the first low-frequency band branch knot are connected to the first feed network in parallel; the second radiator is arranged on a second surface, opposite to the firstsurface, of the dielectric substrate and is provided with a second high-frequency-band branch knot, a second low-frequency-band branch knot and a second feed network; the second high-frequency-band branch knot and the second low-frequency-band branch knot are connected to the second feed network in parallel; the first radiator and the second radiator are in butt joint with each other through the first feed network and the second feed network and are arranged to enable the first high-frequency band branch knot and the second high-frequency band branch knot not to be overlapped and the first low-frequency band branch knot and the second low-frequency band branch knot not to be overlapped. According to the invention, the radiation performance is improved, and the overall size of the dual-frequency dual-polarized antenna is reduced.
Description
technical field [0001] The invention relates to antenna technology, in particular to a dual-frequency dual-polarization antenna. Background technique [0002] The radiator in the existing dual-frequency dual-polarized antenna is composed of two or more high-frequency oscillators and low-frequency oscillators to form a high-frequency oscillator array and a low-frequency array, and the high-frequency oscillator array and the low-frequency oscillator array are respectively insulated and arranged on the reflector. On the same side of the board, there are more components, and the structure of the antenna is more complicated; moreover, the high-frequency oscillator array and the low-frequency oscillator array are arranged in the direction perpendicular to the reflector, resulting in a larger and bulkier antenna. [0003] With the rapid development of the communication industry, there is an urgent requirement for the miniaturization of the antenna, and reducing the size of the ante...
